Solve this problem -x squared -40x- 80 =0
a2+30a+56=0 , solve for a Using the quadratic formula, you will find that: a=-2 , a=-28
By factoring. q2 + 16q = 0 q (q + 16) = 0 Now, either q = 0, or q + 16 = 0. Solve those two equations to get the solution.
9x2-9x = 0 x2-x = 0 x(x-1) = 0 x = 1 or x = 0
x = 12
2sinx+1 equals 0
For y - 2y - 3y equals 0, y equals 0.

"x equals 0" is an equality, not an inequality. The question is, therefore, not consistent.
Suppose x3-4x = 0. To solve, factor: x3-4x = x(x2-4) = x(x+2)(x-2) = 0 Now, a product equals 0 if and only one or more of the factors equals 0, so set each factor to 0 and solve. The roots are 0,-2 and +2.
x: x2 - 81 = 0
Solve this problem -x squared -40x- 80 =0
x=2
10x=x 9x=0 x=0
Divide both sides by 8: m = 0
x=-.25.
-y + y equals 0.
