Some steps to rewrite the expression x3 − 4x + x2 − 4 as a product of three factors are shown below:
step 1: x3 − 4x + x2 − 4
step 2: x3 + x2 − 4x − 4
step 3: x2(x + 1) − 4(x + 1)
which of the following best shows the next two steps to rewrite the expression?
step 4: (x2 − 4)(x + 1); step 5: (x − 2)(x + 2)(x + 1)
step 4: (x2 + 4)(x + 1); step 5: (x + 2)(x + 2)(x + 1)
step 4: (x2 − 4)(x + 1); step 5: (x + 2)(x + 2)(x + 1)
step 4: (x2 + 4)(x + 1); step 5: (x − 2)(x + 2)(x + 1)
