factor 5x^2+12x-32

anonymous · Answer

try doing it by yourself. look for numbers that multiplying gives 5x^2 also the other numbers.

anonymous · Answer

5x^2 + 12x - 32

First, multiply the A term by the C term, or 5 and -32 to get -160

Now, find factors of -160 which add up to be 12 (the B term). These are 20 and -8. Split the B term into these:

5x^2 + 20x - 8x - 32

Now, group:

(5x^2 + 20x) - (8x + 32)

Factor each separately:

5x(x + 4) - 8(x + 4)

Re-group using the common term and you get:

(5x - 8) * (x + 4)
