Multiply: (5x+3)b y(7x+2) (ii) (2x+...

Multiply: `(5x+3)b y(7x+2)` (ii) `(2x+8)b y\ (x-3)`

Text Solution

Verified by Experts

(i)`(5x+3)b y(7x+2)`
Now let us simplify the given expression
`(5x + 3) xx (7x + 2)`
`=5x (7x + 2) + 3 (7x + 2)`
`=35x^2 + 10x + 21x + 6`
`=35x^2 + 31x + 6`

(ii) `(2x+8)b y\ (x-3)`
=Now let us simplify the given expression
`=(2x + 8) xx (x – 3)`
`=2x (x – 3) + 8 (x – 3)`
`=2x^2 – 6x + 8x – 24`
`=2x^2 + 2x - 24`
