Q. What is the product of 6,x2−3x, and x−10 ?Choose 1 answer:(A) −42x+180(B) 6x2−78x+180(C) 6x3−42x2+180x(D) 6x3−78x2+180x
Identify Terms: Identify the terms to be multiplied.We need to multiply the polynomial (6x2−3x) by the binomial (x−10).
Use Distributive Property: Use the distributive property to multiply each term in the first polynomial by each term in the binomial.First, multiply 6x2 by x to get 6x3.Then, multiply 6x2 by −10 to get −60x2.Next, multiply −3x by x to get −3x2.Finally, multiply −3x by −10 to get x1.
Combine Like Terms: Combine like terms.We have 6x3 from the first multiplication.From the second and third multiplications, we combine −60x2 and −3x2 to get −63x2.From the last multiplication, we have 30x.So, the expression becomes 6x3−63x2+30x.
Match with Choices: Match the resulting expression with the given choices.The expression we found is 6x3−63x2+30x, which is not exactly listed in the choices. However, we can see that there is a mistake in the combination of like terms. The correct combination should be −60x2 and −3x2 to get −63x2, which is not one of the choices. We need to re-evaluate our calculations.
