Solution for =-2(3x-2y)(5x+y) equation: 


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

Multiply (3x + -2y) * (5x + y)
0 = -2(3x * (5x + y) + -2y * (5x + y))
0 = -2((5x * 3x + y * 3x) + -2y * (5x + y))

Reorder the terms:
0 = -2((3xy + 15x2) + -2y * (5x + y))
0 = -2((3xy + 15x2) + -2y * (5x + y))
0 = -2(3xy + 15x2 + (5x * -2y + y * -2y))
0 = -2(3xy + 15x2 + (-10xy + -2y2))

Reorder the terms:
0 = -2(3xy + -10xy + 15x2 + -2y2)

Combine like terms: 3xy + -10xy = -7xy
0 = -2(-7xy + 15x2 + -2y2)
0 = (-7xy * -2 + 15x2 * -2 + -2y2 * -2)
0 = (14xy + -30x2 + 4y2)

Solving
0 = 14xy + -30x2 + 4y2

Solving for variable 'x'.
Remove the zero:
-14xy + 30x2 + -4y2 = 14xy + -30x2 + 4y2 + -14xy + 30x2 + -4y2

-14xy + 30x2 + -4y2 = 14xy + -14xy + -30x2 + 30x2 + 4y2 + -4y2

Combine like terms: 14xy + -14xy = 0
-14xy + 30x2 + -4y2 = 0 + -30x2 + 30x2 + 4y2 + -4y2
-14xy + 30x2 + -4y2 = -30x2 + 30x2 + 4y2 + -4y2

Combine like terms: -30x2 + 30x2 = 0
-14xy + 30x2 + -4y2 = 0 + 4y2 + -4y2
-14xy + 30x2 + -4y2 = 4y2 + -4y2

Combine like terms: 4y2 + -4y2 = 0
-14xy + 30x2 + -4y2 = 0
