2. x^2 +6x +8 = (x+4)(x+2)
3. x^2 -7x +12 = (x-4)(x-3)
4. g^2 -2g -24 = (g+4)(g-6)
hope helped
Your calculator says error because you cant have a square root of a negative number because there is no solution to that maybe recheck your equation and try again
Green 5/15
red 2/15
that should be your answer
Y-x =17
y = -x + 17
substitute this into the second equation
y = 4x + 2
-x + 17 = 4x + 2
0= 5x -15
15/5 = 5x/5
3 = x
