Choose the value of c to form a perfect-square trinomial. x2 + 8x + c -8 4 -4 16

c = 16.

Step-by-step explanation:

The c would have to 4^2 (16)  in order to get a middle term of + 8.

x^2 + 8x + 16 = (x + 4)(x + 4).

Complete the square so that the left side of x2 + 8x − 3 = 0 becomes a binomial squared.
