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

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

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

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

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

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

Combine like terms: -3r + -4r = -7r
(3 + -7r + 4r2) = 0

Solving
3 + -7r + 4r2 = 0

Solving for variable 'r'.

Add '-1' to each side of the equation.
1 + -1 + -1r = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -1r = 0 + -1
-1r = 0 + -1

Combine like terms: 0 + -1 = -1
-1r = -1

Divide each side by '-1'.
r = 1

Simplifying
r = 1
Solution
r = {0.75, 1}
