Question

Multiply (3x – 7)(3x – 5)

a. 9x^2 + 6x + 35
b. 9x^2 + 36x + 35
c. 9x^2 – 36x – 35
d. 9x 2 – 36x + 35

Answer 1

9x2−36x+35 that is the answer it was easy

Answer 2

Answer: The required multiplied expression is
`9x^2-36x+35.`

Step-by-step explanation: We are given to multiply the following two linear expressions :

`P=(3x-7)(3x-5).`

To multiply the expressions, we need to multiply each term of one factor with each term of the other.

The multiplication is as follows :

`P\\\\=(3x-7)(3x-5)\\\\=3x(3x-5)-7(3x-5)\\\\=9x^2-15x-21x+35\\\\=9x^2-36x+35.`

Thus, the required multiplied expression is
`9x^2-36x+35.`
