Question

3x^2 + 8x=5x^2-2x solve for x ... please help, these exponents are throwing me off!!

Answer 1

move it all to one side of the equal sign and set it = 0,
then you have
3x^2 + 8x - 5x^2 - 2x = 0
-2x^2 + 10x = 0
now solve for x

Answer 2

it is "+2x", not "-2x"

Answer 3

Thank you! But I'm still having trouble getting x.. how do i get rid of the exponent?

Answer 4

-2x^2 + 10, now try factor -2x out, so
-2x * (something in here) = 0
what do need to multiply -2x by to get -2x^2 + 10x ?

Answer 5

-2x..right?

Answer 6

wait no...

Answer 7

-2x * x = -2x^2
-2x * -5 = +10x
so
-2x * x + -2x * - 5 => -2x * (x - 5) = 0
