Solve x² − 5x + 6 = 0.
Answer: x = 2 or x = 3
Solution: Factor the quadratic as (x − 2)(x − 3) = 0. A product is zero when either factor is zero, giving x = 2 or x = 3.

Evaluate ∫₀¹ 2x dx.
Answer: 1
Solution: An antiderivative of 2x is x². Applying the limits gives 1² − 0² = 1.
-
What is the dot product of two non-zero perpendicular vectors?
Answer: 0
Solution: The dot product is |a||b|cos θ. For perpendicular vectors θ = 90°, and cos 90° = 0.
-
If log₂x = 5, find x.
Answer: 32
Solution: Rewrite the logarithmic equation in exponential form: x = 2⁵ = 32.
-
What is the probability of drawing an ace from a standard 52-card deck?
Answer: 1/13
Solution: There are 4 aces among 52 equally likely cards, so the probability is 4/52, which simplifies to 1/13.
