Question

please help
solve
32x^2-40x-12=-8x+12

Answer 1

set the entire expression equal to zero
try and solve that out for now and tag me when you done that

Answer 2

\[32x^2-38x-24=0 \]

Answer 3

do i start from this? @Will.H

Answer 4

Starting from "32x^2-40x-12=-8x+12," manipulate the equation so that all terms are on the left side. The right side will automatically be 0 if you'd do that.

Simplify the left side as much as possible. You should get 3 terms. Write them in descending order by powers of x.

Your result?

Answer 5

32x^2-38x-24=0
i think..

Answer 6

HI!!

Answer 7

i think so too

Answer 8

oh actually there is an arithmetic mistake there

Answer 9

\[-40+8=-32\]

Answer 10

start with \[32x^2-32x-24=0 \]

Answer 11

oh sorry bout the mistake !

Answer 12

then divide by the greatest common factor first

Answer 13

if that is not clear, divide by 8 , since 8 goes in to each term evenly and get\[4x^2-4x+3=0\] which, by some miracle, factors

Answer 14

or use the famous quadratic formula
\[\frac{ -b \pm \sqrt{b^2 -4ac} }{ 2a }\]
