Question

Multiply the following polynomials and write the number of polynomials in the answer. (x^2-4x+8) (x^2-1)​

Answer 1

Answer:

)p(x)×q(x)=(x

2

−9)×(6x

2

+7x−2)

=6x

4

+7x

−2x}2) (x) \times x (7x + 2) \times (15x - 9) \\ = 105 {x}^{2} - 63x + 30x - 18 \\ = 105 {x}^{2} - 33x - 18 \\ degree \: 2\end{gathered}

2)f(x)×g(x)=(7x+2)×(15x−9)

=105x

2

−63x+30x−18

=105x

−33x−18

\begin{gathered}3)h(x) \times f(x) = (6 {x}^{2} - 7x + 1) \times (5x - 7) \\ = 30 {x}^{3} - 42 {x}^{2} - 35 {x}^{2} + 9x + 5x - 7 \\ = 30 {x}^{3} - 77 {x}^{2} + 14x - 7 \\ degree \: 3\end{gathered}

3)h(x)×f(x)=(6x

2

−7x+1)×(5x−7)

=30x

−42x

2

−35x

+9x+5x−7

=30x
