Question

In the process of completing the square, 3x2 + 7x - 12 becomes x^2+7/4x=4

true or false

Answer 1

False.

because in the process of completing the square,
`3x^2+7x-12 = 0` become
`x^2+(7)/(3)x = 4` but not
`x^2+(7)/(4)x = 4`

Explanation:

Given the equation:
`3x^2+7x-12 = 0`

Divide both sides by 3 we get;

`x^2+(7)/(3)x -4=0`

Add 4 to both sides we have;

`x^2+(7)/(3)x -4+4=0+4`

Simplify:

`x^2+(7)/(3)x = 4`

In the process of completing the square,
`3x^2+7x-12 = 0` becomes
`x^2+(7)/(3)x = 4` not
`x^2+(7)/(4)x = 4`

Therefore, the statement is FALSE.
