Solution for x(7x+1)(x-3)=0 equation:


Simplifying
x(7x + 1)(x + -3) = 0

Reorder the terms:
x(1 + 7x)(x + -3) = 0

Reorder the terms:
x(1 + 7x)(-3 + x) = 0

Multiply (1 + 7x) * (-3 + x)
x(1(-3 + x) + 7x * (-3 + x)) = 0
x((-3 * 1 + x * 1) + 7x * (-3 + x)) = 0
x((-3 + 1x) + 7x * (-3 + x)) = 0
x(-3 + 1x + (-3 * 7x + x * 7x)) = 0
x(-3 + 1x + (-21x + 7x2)) = 0

Combine like terms: 1x + -21x = -20x
x(-3 + -20x + 7x2) = 0
(-3 * x + -20x * x + 7x2 * x) = 0
(-3x + -20x2 + 7x3) = 0

Solving
-3x + -20x2 + 7x3 = 0

Solving for variable 'x'.
