Question

Complete the square: 3x^2+7x-12 becomes x^2+7/4x=4 T or F?

Answer 1

\( 3x^2+7x-12 = 0 \)

First you must divide both sides by 3. you need \(x^2\) by itself.

Answer 2

first , coefficient of x^2 must be 1,so divide by 3

Answer 3

\( \dfrac{3}{3}x^2+\dfrac{7}{3} x -\dfrac{12}{3} = 0 \)

Answer 4

x^2+7/3x+4=0?

Answer 5

so it;s fasle?

Answer 6

Good.
\( x^2+\dfrac{7}{3} x - 4 = 0 \)

\( x^2+\dfrac{7}{3} x = 4 \)

Answer 7

False.
You are correct.

Answer 8

Yay! Thank you!
