Solution for x(7x+1)(x-5)=0 equation:


Simplifying
x(7x + 1)(x + -5) = 0

Reorder the terms:
x(1 + 7x)(x + -5) = 0

Reorder the terms:
x(1 + 7x)(-5 + x) = 0

Multiply (1 + 7x) * (-5 + x)
x(1(-5 + x) + 7x * (-5 + x)) = 0
x((-5 * 1 + x * 1) + 7x * (-5 + x)) = 0
x((-5 + 1x) + 7x * (-5 + x)) = 0
x(-5 + 1x + (-5 * 7x + x * 7x)) = 0
x(-5 + 1x + (-35x + 7x2)) = 0

Combine like terms: 1x + -35x = -34x
x(-5 + -34x + 7x2) = 0
(-5 * x + -34x * x + 7x2 * x) = 0
(-5x + -34x2 + 7x3) = 0

Solving
-5x + -34x2 + 7x3 = 0

Solving for variable 'x'.
