The following equation is being multiplied by the LCD. Complete the multiplication to eliminate the denominators.The resulting equation is

x + 2 – 1 = x – 3

3x(x + 2) – (x – 2) = x – 3

(x – 2)(x + 2) – 1 = (x – 3)(x – 2)

(x – 2)(x + 2) – 3x = (x – 2)(x – 3)

The solutions to 15(2a – 2) = 5(a2 – 1) are:

a = 1, a = –1

a = 5, a = –1

a = 5, a = 1

Question text not available

15(a2 – 1) = 5(2a – 2)

15(2a – 2) = 5(a2 – 1)

15(a2 – 1)(2a – 2) = 5(2a – 2)(a2 – 1)
