16? using 16, you have (3x2 + 4)(3x2 + 4) = 9x2 + 24x + 16

3x - 24x + 5 + 3 = -21x + 8

The idea is to take half the coefficient of the linear term (in this case, of 24), and square it. This will be the value for "c".

(x^2) + 24x + 144 = -9 x = -12

factor the trinomial 16x^2+24x+9

3x - 24x + 5 + 3 = -21x + 8

144

3(2) + 24x + 48 = 0 6 + 24x + 48 = 0 24x + 54 = 0 24x + 54 - 54 = 0 - 54 24x = -54 24x/24 = -54/24 x = -9/4 x = -2 1/4
