Question

If ​P(x)=9x and R(x)=9x-4,find P(x)*R(x)

Answer 1

The product of the polynomials P(x) = 9x and R(x) = 9x - 4 is P(x)*R(x) =
`81x^2 - 36x`

To find the product of two polynomials P(x) and R(x), we simply need to multiply each term in the first polynomial by each term in the second polynomial. In this particular case, we need to find P(x)*R(x), where P(x) = 9x and R(x) = 9x - 4.

Multiplying these two gives:

P(x)*R(x) = (9x)*(9x - 4)

= 9x*9x - 9x*4

= 81x2 - 36x

So the product P(x)*R(x) equals 81x2 - 36x.
