Which are steps in the process of completing the square used to solve the equation 3 - 4x = 5x2 - 14x? Check all that apply 3 = 5 (x2 + 2x) 3 = 5x2 - 10x 4 = 5 (x2 - 2x + 1) 8 = 5 (x2 - 2x + 1) 3 = 5 (x - 1) 2 4 = 5 (x - 1) 2 StartFraction 8 Over 5 EndFraction = (x - 1) 2

1. 3 = 5x2 - 10x

2. 8 = 5 (x2 - 2x + 1)

3. StartFraction 8 Over 5 EndFraction = (x - 1) 2

Step-by-step explanation:

3-4x=5x^2-14x

3=5x^2-14x+4x

3=5x^2-10x

5x^2-10x-3=0

1. 3 = 5x2 - 10x

2. 8 = 5 (x2 - 2x + 1)

8=5x^2-10x+5

8-5=5x^2-10x

3=5x^2-10x

3. StartFraction 8 Over 5 EndFraction = (x - 1) 2

8/5=x^2-2x+1

Cross product

8=5 (x^2-2x+1)

8=5x^2-10x+5

8-5=5x^2-10x

3=5x^2-10x
