Question

Determine the factors of 3x2 + 10x - 8.

(3x - 8)(x + 1)
(3x - 1)(x + 8)
(3x - 4)(x + 2)
(3x - 2)(x + 4)

Answer 1

are you familiar with foil?

Answer 2

p.s. the 3x2 is actually 3^2

Answer 3

(3x ? )*(x ? )

Answer 4

Im thinking D

Answer 5

that would take care of the 3x^2 now you need to fill in the rest to come up numbers that would work when you foil

Answer 6

well, Im still going with D...when I multiply all of the numbers and add them together they form this equation......do you mind helping me with one more?

Answer 7

sure

Answer 8

i agree with d as well

Answer 9

Perfect..hang on

Answer 10

Select the factors of 6ab + 3ay - 2bx - xy.

(3a - x) (2b + y)
(3a - y)(2b + x)
(2a - x)(3b + y)
(2a - y)(3b + x)

Answer 11

same as the last. we can foil the answers to see what works. or you can try to work from the question to factor it.

Answer 12

Is is A?

Answer 13

id say so
