(15x+15)(-1+16x)=

Solution for (15x+15)(-1+16x)= equation:

Simplifying
(15x + 15)(-1 + 16x) = 0

Reorder the terms:
(15 + 15x)(-1 + 16x) = 0

Multiply (15 + 15x) * (-1 + 16x)
(15(-1 + 16x) + 15x * (-1 + 16x)) = 0
((-1 * 15 + 16x * 15) + 15x * (-1 + 16x)) = 0
((-15 + 240x) + 15x * (-1 + 16x)) = 0
(-15 + 240x + (-1 * 15x + 16x * 15x)) = 0
(-15 + 240x + (-15x + 240x2)) = 0

Combine like terms: 240x + -15x = 225x
(-15 + 225x + 240x2) = 0

Solving
-15 + 225x + 240x2 = 0
