Solution for (2r-3)(r-10)=0 equation:


Simplifying
(2r + -3)(r + -10) = 0

Reorder the terms:
(-3 + 2r)(r + -10) = 0

Reorder the terms:
(-3 + 2r)(-10 + r) = 0

Multiply (-3 + 2r) * (-10 + r)
(-3(-10 + r) + 2r * (-10 + r)) = 0
((-10 * -3 + r * -3) + 2r * (-10 + r)) = 0
((30 + -3r) + 2r * (-10 + r)) = 0
(30 + -3r + (-10 * 2r + r * 2r)) = 0
(30 + -3r + (-20r + 2r2)) = 0

Combine like terms: -3r + -20r = -23r
(30 + -23r + 2r2) = 0
