Hello everyone, I need help with one more question and that's using the quadractic formula to solve 16*x*2 + 96*x* + 128 = 0 and -4*x*2 + 28*x* – 48 = 0. Could someone tell me the answer to both so I can hurry and submit the assignment, I've been really waiting to see what I get on this.

\(\displaystyle 16x^2 + 96x + 128 = 0\)

divide every term by 16 ....

\(\displaystyle x^2 + 6x + 8 = 0\)

this is a factorable quadratic ... do it.

---------------------------------------

\(\displaystyle -4x^2 + 28x - 48 = 0\)

start by dividing every term by -4 ... same song, second verse.
