Q(x) = -4x + 2x - 3 + 2x - x2 - 2
Q(x) = (-4x + 2x + 2x) + (-3 - 2) +- x2
Q(x) = 0x + (-5) - x2
Q(x) = -5 - x2
Q(x) = -4x + 2x - 3 + 2x - x2 - 2
= (-4x + 2x + 2x) (-3 - 2) - x2
= -5 - x2 = -x2 - 5
\(Q\left(x\right)=-4x+2x-3+2x-x^2-2\)
\(\rightarrow Q\left(x\right)=-x^2+\left(-4x+2x+2x\right)+\left(-3-2\right)\)
\(Q\left(x\right)=-x^2-5\)
