x2+24x+144 = 9 x2+24x+144-9 = 0 x2+24x+135 = 0 (x+9)(x+15) = 0 x = -9 or x = -15
Easy, peasy! x2 + 7x - 144 = (x + 16)(x - 9).
x2 + y2 = 144 = radius squared radius = sqrt (144) = 12 diameter = 2 x radius = 24
please help on this x2+6x+27=
x2+7x+12
144X = X2 144X - X2 = 0 (144 - X)X = 0 X = 0 or X = 144
Im assuming you mean x2 (x squared). This equation will be a quadratic. so... x2+144=-24x subtract -24x from itself and the other side -24x -24x ----------------- x2-24x+144=0 now break it down even further (x-12)(x-12)=0 Now you solve the "mini-equations" x-12=0 x-12=0 +12 +12 +12 +12 --------------------------- x=12 or x=12 hope it helps!!!

Easy, peasy! x2 + 7x - 144 = (x + 16)(x - 9).
X4 - 144 (X2 - 12)(X2 + 12) As there is no linear term I see no further factoring.
x2 + y2 = 144 = radius squared radius = sqrt (144) = 12 diameter = 2 x radius = 24
