Question

X value in 5x^2-136=44

Answer 1

x=6

Explanation:

5*x^2-136-(44)=0

(5x^2-136)-44=0

5x^2-180=5*(x^2-36)

5*(x+6)*(x-6)=0

x=6

Answer 2

Add 136 to both sides

5x^2 = 44 + 136

Simplify 44 + 136 to 180

Divide both sides by 5

x^2 = 180/5

Simplify 180/5 to 36

x^2 = 36

Take the square root of both sides

x = ± √36

Since 6 × 6 = 36, the square root of 36 is 6

x = 6
