Question

Solve for x in the equation 2x^2-5+1=3

Answer 1

Answer:

x = 2

Step-by-step explanation:

Given

2x^2-5+1=3

Combine like terms

-5 + 1 = -4

2x^2 - 4 = 4

Add 4 to both sides

2x^2 = 8

Divide both sides by 2

8/2 = 4

Simplify

x^2 = 4

Square both sides

$\sqrt{x^2} = x$

$\sqrt{4}=2$

Simplify

x = 2

Answer

x = 2
