No, It's not.
coefficients for perfect square would be:
3² - 2(3)(6) + 6² = 9 - 36 + 36
Answer: 3x + 6 -4x = 1
Simplify to -x + 6 = 1 because 3x - 4x = -1x
Answer:
for this equation one factor is (x+6) and the other is (x-4)
1) (-7,2)
y=2, -x+4=11, -x=11-4=7, x=-7
2) (-3,4)
-x+2y=11
y=4, -x+8=11, -x=3, x=-3
3) (1,6)
-x+2y=11
y=6, -x+12=11,-x=-1, x=1
