Question

Determine the factors of x2 − 7x − 10.
A. (x + 2)(x − 5)
B. Prime
C. (x − 2)(x + 5)
D. (x + 10)(x − 1)

Answer 1

Determine the factors of x2 − 9x + 20.
A. (x + 4)(x + 5)
B. (x − 4)(x − 5)
C. (x + 2)(x + 10)
D. (x − 2)(x − 10)

Answer 2

remember the formula
\[x^{2}+ (a+b)x+(a*b) \]

Answer 3

so what you're looking for is two numbers that add to -7 and mulitply to -10
and/or the second problem add to -9 multiply to 20

Answer 4

I personally can't think of a solution to the first posted problem I would go with "Prime"
