Solution for 0=(5x-7)(3x-2) equation:


Simplifying
0 = (5x + -7)(3x + -2)

Reorder the terms:
0 = (-7 + 5x)(3x + -2)

Reorder the terms:
0 = (-7 + 5x)(-2 + 3x)

Multiply (-7 + 5x) * (-2 + 3x)
0 = (-7(-2 + 3x) + 5x * (-2 + 3x))
0 = ((-2 * -7 + 3x * -7) + 5x * (-2 + 3x))
0 = ((14 + -21x) + 5x * (-2 + 3x))
0 = (14 + -21x + (-2 * 5x + 3x * 5x))
0 = (14 + -21x + (-10x + 15x2))

Combine like terms: -21x + -10x = -31x
0 = (14 + -31x + 15x2)
