(3r-1)(4r-3)=

Solution for (3r-1)(4r-3)= equation:

Simplifying
(3r + -1)(4r + -3) = 0

Reorder the terms:
(-1 + 3r)(4r + -3) = 0

Reorder the terms:
(-1 + 3r)(-3 + 4r) = 0

Multiply (-1 + 3r) * (-3 + 4r)
(-1(-3 + 4r) + 3r * (-3 + 4r)) = 0
((-3 * -1 + 4r * -1) + 3r * (-3 + 4r)) = 0
((3 + -4r) + 3r * (-3 + 4r)) = 0
(3 + -4r + (-3 * 3r + 4r * 3r)) = 0
(3 + -4r + (-9r + 12r2)) = 0

Combine like terms: -4r + -9r = -13r
(3 + -13r + 12r2) = 0

Solving
3 + -13r + 12r2 = 0
