(x-5)(-2x+6)=0

Solution for (x-5)(-2x+6)=0 equation:

Simplifying
(x + -5)(-2x + 6) = 0

Reorder the terms:
(-5 + x)(-2x + 6) = 0

Reorder the terms:
(-5 + x)(6 + -2x) = 0

Multiply (-5 + x) * (6 + -2x)
(-5(6 + -2x) + x(6 + -2x)) = 0
((6 * -5 + -2x * -5) + x(6 + -2x)) = 0
((-30 + 10x) + x(6 + -2x)) = 0
(-30 + 10x + (6 * x + -2x * x)) = 0
(-30 + 10x + (6x + -2x2)) = 0

Combine like terms: 10x + 6x = 16x
(-30 + 16x + -2x2) = 0
