Step-by-step explanation:
1.) Use the Distributive Property to multiply 7x² + 9x – 12 by 2x –5 and combine like terms.
Divide 7x² –10x –8 by x –2 using long polynomial division.
Smiplify the expression.
4.) Cancel out 38a in both numerator and denominator.
To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent.
Anything divided by -1 gives it's opposite.
5.) To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent. Subtract 5 from 8 to get 3.
Calculated 3 to the power of 3 and get 27.
