Find the least common multiple of x2 – 2x – 15 and x2 + 2x – 3.

  x^3 -3x^2 -13x +15

Step-by-step explanation:

The LCM is the product of unique factors, so the first step is to find the factors of each expression.

  x^2 -2x -15 = (x -5)(x +3)

  x^2 +2x -3) = (x -1)(x +3)

The unique factors are (x -5), (x +3), (x -1). The LCM is their product, which we can compute by multiplying the first expression by the factor it does not contain:

  LCM( ) = (x -1)(x^2 -2x -15) = x^3 -3x^2 -13x +15

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
