Distribute the first term over the second binomial, and distribute the second term, which is 1, of the first binomial over the second binomial.

How to square binomials. Add the foil terms you just calculated together; In this case the terms were y 2, 8 y , 8 y and 64, so you have: Identify a as the first term in the trinomial, b as the second term, and c as the third term.

Y^2 + 8y + 8y + 64 y2. So if we're asked to square a binomial, all we have to do is square the coefficient of x, square the constant term, find twice the product of the coefficient and the constant, and then we just. We have a binomial raised to the power of 4 and so we look at the 4th row of the pascal’s triangle to find the 5 coefficients of 1, 4, 6, 4 and 1.

We start with (2𝑥) 4. What is square of binomials? The square of a binomial is always a trinomial.

( a + b) 2 = a 2 + 2 a b + b 2. The square of the first terms twice the product of the two terms and the square of the last term. The result will be the square of the binomial.

Step 2:write each term as a perfect cube. To factor binomials with exponents to the second power, take the square root of the first term and of the coefficient that follows. The square of a binomial is the sum of:

Factor out the gcf if necessary. We’ll look at each part of the binomial separately. This is called the binomial square.
