Solution for 2*(x+5)*(3-4x)=0 equation:


Simplifying
2(x + 5)(3 + -4x) = 0

Reorder the terms:
2(5 + x)(3 + -4x) = 0

Multiply (5 + x) * (3 + -4x)
2(5(3 + -4x) + x(3 + -4x)) = 0
2((3 * 5 + -4x * 5) + x(3 + -4x)) = 0
2((15 + -20x) + x(3 + -4x)) = 0
2(15 + -20x + (3 * x + -4x * x)) = 0
2(15 + -20x + (3x + -4x2)) = 0

Combine like terms: -20x + 3x = -17x
2(15 + -17x + -4x2) = 0
