Question

If the quadratic formula is used to solve 2x2 = 8x - 3, what are the solutions?

Answer 1

Explanation:

if 2x^2 = 8x - 3

Move terms to the left side

2x^{2}=8x-3

2x^{2} - (8x - 3)= 0

Distribute

2x^{2}-8x+3=0

Use quadratic formula

x=8± √-8^2-4*2*

2*2

Simplify

x=8± 2√ 10

4

Separate the equations

x=4- √ 10

2

x=4+ √ 10

2

Solve

x=4-3.2 = 0.4

2

x= 4+3.2 = 3.6
