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
Answer:
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
