1Simplify the algebraic fraction by factoring: (x^3 - 8) / (x^2 - 4) for all x != ±2.
A.(x^2 + 2x + 4) / (x + 2)
B.(x^2 - 2x + 4) / (x + 2)
C.(x^2 + 4) / (x + 2)
D.(x - 2) / (x + 2)
Explanation: Factoring the numerator as a difference of cubes: x^3 - 8 = (x - 2)(x^2 + 2x + 4). Factoring the denominator as a difference of squares: x^2 - 4 = (x - 2)(x + 2). Canceling (x - 2) gives (x^2 + 2x + 4) / (x + 2).
2Rationalize the denominator of the expression: 6 / (sqrt(5) - sqrt(2)).
A.2(sqrt(5) - sqrt(2))
B.2(sqrt(5) + sqrt(2))
C.6(sqrt(5) + sqrt(2)) / 7
D.sqrt(5) + sqrt(2)
Explanation: Multiply numerator and denominator by the conjugate (sqrt(5) + sqrt(2)): 6(sqrt(5) + sqrt(2)) / [(sqrt(5))^2 - (sqrt(2))^2] = 6(sqrt(5) + sqrt(2)) / (5 - 2) = 6(sqrt(5) + sqrt(2)) / 3 = 2(sqrt(5) + sqrt(2)).
3What is the remainder when the polynomial P(x) = 2x^3 - 5x^2 + 4x - 7 is divided by (x - 2)?
A.3
B.-5
C.-3
D.1
Explanation: By the Remainder Theorem, the remainder of P(x) divided by (x - 2) is P(2). Evaluating: P(2) = 2(2)^3 - 5(2)^2 + 4(2) - 7 = 2(8) - 5(4) + 8 - 7 = 16 - 20 + 8 - 7 = -3.
4Find the discriminant and nature of the roots for the quadratic equation 3x^2 - 4x + 2 = 0.
A.Δ = 40; two distinct real roots
B.Δ = 0; one repeated real root
C.Δ = -4; two distinct real roots
D.Δ = -8; two complex conjugate roots
Explanation: The discriminant is Δ = b^2 - 4ac = (-4)^2 - 4(3)(2) = 16 - 24 = -8. Since Δ < 0, the equation has two distinct complex conjugate roots (no real solutions).
5Solve the absolute value inequality: |2x - 3| < 7.
A.-2 < x < 5
B.x < -2 or x > 5
C.-5 < x < 5
D.x < 5
Explanation: |2x - 3| < 7 is equivalent to -7 < 2x - 3 < 7. Adding 3 across the compound inequality gives -4 < 2x < 10. Dividing by 2 yields -2 < x < 5.
6What is the distance from the point P(2, 3) to the line given by the equation 4x - 3y + 11 = 0?
A.3
B.2
C.4
D.5
Explanation: Using the point-to-line distance formula d = |Ax0 + By0 + C| / sqrt(A^2 + B^2): d = |4(2) - 3(3) + 11| / sqrt(4^2 + (-3)^2) = |8 - 9 + 11| / sqrt(16 + 9) = |10| / sqrt(25) = 10 / 5 = 2.
7Find the sum of all solutions to the equation x + 6/x = 5.
A.6
B.1
C.5
D.-5
Explanation: Multiplying both sides by x (x != 0) gives x^2 + 6 = 5x -> x^2 - 5x + 6 = 0. Factoring: (x - 2)(x - 3) = 0, so solutions are x = 2 and x = 3. Their sum is 2 + 3 = 5 (or directly by Vieta's formulas, sum = -b/a = -(-5)/1 = 5).
8What is the 5th term in the binomial expansion of (x + 2y)^6?
A.160 x^2 y^4
B.60 x^4 y^2
C.240 x^3 y^3
D.240 x^2 y^4
Explanation: The (k+1)-th term in (a + b)^n is T_(k+1) = C(n, k) * a^(n-k) * b^k. For the 5th term (k = 4, n = 6): T_5 = C(6, 4) * x^(6-4) * (2y)^4 = 15 * x^2 * (16 y^4) = 240 x^2 y^4.
9Find all solutions to the trigonometric equation sin(2x) - cos(x) = 0 in the interval [0, 2π).
A.x = π/6, 5π/6
B.x = π/6, π/2, 5π/6, 3π/2
C.x = π/3, 2π/3, 4π/3, 5π/3
D.x = 0, π/2, π, 3π/2
Explanation: Use the double angle identity sin(2x) = 2 sin(x) cos(x). The equation becomes 2 sin(x) cos(x) - cos(x) = 0 -> cos(x)[2 sin(x) - 1] = 0. Case 1: cos(x) = 0 -> x = π/2, 3π/2. Case 2: sin(x) = 1/2 -> x = π/6, 5π/6. The complete set in [0, 2π) is {π/6, π/2, 5π/6, 3π/2}.
10In a triangle ABC, side a = 7, side b = 5, and side c = 8. What is the cosine of angle C (cos C)?
A.2/7
B.1/5
C.1/7
D.3/7
Explanation: By the Law of Cosines, c^2 = a^2 + b^2 - 2ab cos(C) -> 8^2 = 7^2 + 5^2 - 2(7)(5) cos(C) -> 64 = 49 + 25 - 70 cos(C) -> 64 = 74 - 70 cos(C) -> 70 cos(C) = 10 -> cos(C) = 10/70 = 1/7.
