Question

PLEASE SOMEONE HELP ASAP

1. conjugate -5+√x
2. conjugate 7-√b
-Please give an explanation!!

Answer 1

1.
`-5-√(x)`

2.
`7+√(b)`

Explanation:

The conjugate of a radical expression

`a+√(b)`

is the expression

`a-√(b)`

And vice-versa.

The conjugate is mostly used to rationalize radical expressions because the expression by its conjugate produces another expression without the radicals.

The question asks to find the conjugate of:

1.
`-5+√(x)`

The conjugate is

`-5-√(x)`

2.
`7-√(b)`

The conjugate is

`7+√(b)`
