allochka39001 [22]

Answer:

Step-by-step explanation:

To find the answer, you have to multiply each term of the first parenthesis' expression with each term in the next parenthesis' expression. Then combine like terms. So we have:

$(6x^2-6x-5)(7x^2+6x-5)\\=(6x^2)(7x^2)+(6x^2)(6x)+(6x^2)(-5)+(-6x)(7x^2)+(-6x)(6x)+(-6x)(-5)+(-5)(7x^2)+(-5)(6x)+(-5)(-5)\\=42x^4+36x^3-30x^2-42x^3-36x^2+30x-35x^2-30x+25\\=42x^4-6x^3-101x^2+25$

Answer choice B is right.
