x^2 +4x-32=0
(x-4)(x+8)=0
then x-4=0 x+8=0
x=4 x=-8

The highest power of the variable is 2, so it is a second degree polynomial.
(x - 4) or (x + 8)
... and what is the question?
4x + 3 doesn't factor. It is in its simplest form.
4X + 7Y = 60 -4X + 7Y = - 4 -----------------------+ 14Y = 56 Y = 4 --------- insert back into one of these equations to find X 4X + 7(4) = 60 4X + 28 = 60 4X = 32 X = 8 ------------check 4(8) + 7(4) = 60 32 + 28 = 60 60 = 60 ----------------checks, now second equation -4(8) + 7(4) = -4 -32 + 28 = -4 -4 = -4 --------------checks solution set. X = 8 Y = 4 (8,4)
