Question

factor this 15=8x^2-14x

Answer 1

ok, so first you must subtract 15 on both sides, to get the three terms:
15=8x^2-14x
0=8x^2-14x-15

Answer 2

\[0=8x^2-14x-15 \]

Answer 3

ill brb

Answer 4

what e thos pic mathfreak

Answer 5

ok, sorry im back

Answer 6

so now we have to sind a value that when multiplied, it equals -15.

Answer 7

the only two numbers that could equal -15, would be -3*5, or -5*3

Answer 8

lets first try 3*-5
(4x+3)(2x-5) next we multiply it out and see if we get back to our original problem. :15=8x^2-14x

Answer 9

(4x+3)(2x-5)
8x^2-20x+6x-15
8x^2-14x-15.

we know this is right, because we got back to:8x^2-14x-15

Answer 10

so (4x+3)(2x-5) is the right answer

Answer 11

when we multiply that out, we get :
x^2+2x-3. which means this is right. remember how we divided -6x^2? well this is when we put it back. so the final factored answer is:
-6x^2(x^2+2x-3)

Answer 12

sorry, wrong place
