No it is a linear one. X^2 = quadratic, x = linear. So if the equation doesn't have an x squared, then it is not quadratic.
144
x = 27
x+27=43 x+27-27=43-27 x+0=16
r^2 - 12r + 27 what two factors of 27 add up to - 12? (r - 3)(r - 9) FOIL that and get the quadratic polynomial back
The slope is -5/3.
No
The discriminant is -27 and so there are no real roots.
a2 + 12a + 27 = (a + 3)(a + 9)

16 plus 27 equals 43.
(5x - 3)(7x + 9)
55 + 27 + 65 = 147
36+27=63
27 + 20 = 47
