Solve each equation below for x. Show all of your work. (Assume denominators of zero are already excluded.) Homework Help ✎
cx – a = b
– b2 = c
(x – a)(x – b) = 0
ax3 – acx2 = 0
+ a = b
x = ab2 + ac
x = a, b
Factor and use the Zero Product Property.
Multiply both sides by the common denominator, c(a + b).
Subtract a from both sides and then multiply both sides by x3.
Isolate and solve for x.
