Question

HELP ME PLEASE HELP I NEED HELP PLEASE :( !!

Answer 1

Expression: (-2x^3 + x - 5) × (x^3 - 3x - 4)

a) First thing you need to do if find like terms.

• -2x^3 and x^3 are like terms

• x and -3x are like terms

• -5 and -4 are like terms

Now, multiply each like term.

• -2x^3 × x^3 = -2x^3

• x × -3 = -3

• -5 × -4 = 20

Put these products into new expression.

-2x^3 -3 +20 <=== that's your product!

b)

The products are equal because it is the same expression, just that the places of the numbers have changed.
