Question

Q(x)= -4x³+2x-3+2x-x²-2

thu gọn đa thức

Answer 1

Q(x) = -4x³ + 2x - 3 + 2x - x² - 2

= -4x³ + ( 2x + 2x ) + ( -3 - 2 ) - x²

= -4x³ + 4x - 5 - x²

Answer 2

Q(x) = -4x³+2x-3+2x-x²-2

= -4x³-x²+(2x+2x)-(3+2)

= -4x³-x²+4x-5

Answer 3

\(Q\left(x\right)=-4x^3+2x-3+2x-x^2-2\)

\(=-4x^3+4x-x^2-5\)

\(=-4x^3-x^2+4x-5\)

Answer 4

Q_(x)= -4x³ + 2x - 3 + 2x - x² - 2

= -4x³- x² + 2x + 2x - 3 - 2

= -4x³ -x² + 4x - 5

Answer 5

\(Q\left(x\right)=-4x^3+2x-3+2x-x^2-2\)

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

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