Answer:
The factored form is (3+ x^2)(5 + 2x)
Step-by-step explanation:
I.I rewrited it as 15 + 5x^2 + 6x + 2x^2
= 5(3 + x^2) + 2x(3 + x^2)
= [tex](3 + x^{2})(5 + 2x^{})[/tex]
II. Prove by
= 3(5) + 3(2x) + x^2(5) + x^2(2x)
= 15 + 6x + 5x^2 + 2x^3
That makes = 2x^3 + 5x^2 + 6x + 15
Ask me for anything.
