Solution for 0=(-2-a)(5-b) equation:


Simplifying
0 = (-2 + -1a)(5 + -1b)

Multiply (-2 + -1a) * (5 + -1b)
0 = (-2(5 + -1b) + -1a * (5 + -1b))
0 = ((5 * -2 + -1b * -2) + -1a * (5 + -1b))
0 = ((-10 + 2b) + -1a * (5 + -1b))
0 = (-10 + 2b + (5 * -1a + -1b * -1a))
0 = (-10 + 2b + (-5a + 1ab))

Reorder the terms:
0 = (-10 + -5a + 1ab + 2b)
0 = (-10 + -5a + 1ab + 2b)
