Question

Add5x2+12x2-4x-16 to the product of 7x2-4x+5 and 3x-2

Answer 1

Step-by-step explanation:

please make a correction in the question-

Add 5x²... is wrong and 5x³...is correct.

so Im taking 5x³

(7x²-4x+5)(3x-2)+5x³+12x²-4x-16

21x³-14x²-12x²+8x+15x-10+5x³+12x²-4x-16

21x³+5x³-26x²+12x²+23x-4x-10-16

26x³-14x²+19x-26
