Question

if i were to simplify the equation 8x^2 + 2x = 3 , would i divided both sides by 8??

Answer 1

I would use the quadratic formula

Answer 2

i have to factor

Answer 3

8x^2 + 2x = 3

8x^2 + 2x - 3 = 0

8x^2 + 6x - 4x - 3 = 0

Now factor by grouping

Answer 4

where did you get the 6 and -4 from?

Answer 5

Multiply 8 and -3 to get -24

Now find two numbers that

a) multiply to -24

AND

b) add to 2

These two numbers are 6 and -4

So we break up 2x into 6x-4x
