Compare and contrast a perfect square trinomial and a general quadratic trinomial​

The ahead we can see some binomials that have been squared.

Our polynomial tour guide tells us that one special case of factoring involves squared binomials. Our guide leans in close and whispers another little trick in our ears (because we just don't have enough of those):

"The product of a squared binomial is a perfect square trinomial."

She then passes us a note with the following on it:

(a + b)² = (a + b) (a + b) = a² + 2ab + b²

(a – b)² = (a – b) (a – b) = a²– 2ab + b²

She then nods, factors herself into a squared binomial, and rolls down the mountain. Well, that was weird.

the first and last terms of the trinomial are both perfect squares, and that the trinomial's middle term is . Also note that the sign before the middle term matches the sign in the binomial

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
