What is 6x^2+60x+150=0?

Answer: x = - 5twice

Step-by-step explanation:

6x2+60x+150=0

Quadratic equation

But firstly, divide all by 6

6x2/6+60x/6+150/6=0

X2+10x+25=0

Variable of 25 that will give 10 is 5&5

Substitute

X2+5x+5x+25=0

X (x+5) + 5 (x+5) = 0

(X+5) (x+5) = 0

X+5=0

X = - 5 twice

6x²+60x+150=0

36x+60x = - 150

96x = - 150

x = - 1.56
