The product of a binomial and a trinomial is x 3 + 3 x 2 − x + 2 x 2 + 6 x − 2. which expression is equivalent to this product after it has been fully simplified?

x3 + 5x2 + 5x – 2
x3 + 2x2 + 8x – 2
x3 + 11x2 – 2
x3 + 10x2 – 2

If you would like to find the equivalent expression, you can calculate this using the following steps:

x^3 + 3 * x^2 - x + 2 * x^2 + 6 * x - 2 = x^3 + 3 * x^2 + 2 * x^2 - x + 6 * x - 2 = x^3 + 5 * x^2 + 5 * x - 2

The correct result would be x^3 + 5 * x^2 + 5 * x - 2.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
