Answer:
You need to multiply the polynomials. Please see attached picture for answer.
= 4x ^4 + -10x^3 + 15x^2 + 7x +5
Step-by-step explanation:
You need to multiply each term step by step
(4x ^2+2x+1)*(x^2) + (4x ^2+2x+1)*(-3x) + (4x ^2+2x+1)*5
= (4x ^4 + 2x^3 +x^2) + (-12x ^3 - 6x^2 -3x) + (20x ^2+10x+5)
= 4x ^4 + -10x^3 + 15x^2 + 7x +5
