X value in 5x^2-136=44

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

x=6

Step-by-step 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
