Please help me solve for x : 10x^2+70x=180
Standard form
10x^2 + 70x - 180 = 0
Simplify, divide by 10:
x^2 + 7x - 18 = 0
Factors to:
(x+9)(x-2) = 0
Two solutions
x = -9
x = +2
:
:
Check solution in original problem using x=-9
10x^2 + 70x = 180
10(-9^2) + 70(-9) = 180
10(81) - 630 = 180
810 - 630 = 180
:
You can check the x=2 solution

10x^2+70x=180
10X^2+70X-180=0
10(X^2+7X-18)=0
10(X+9)(X-2)=0
X=9=0
X=-9 ANS.
X-2=0
X=2 ANS.
