Question

Which choice is equivalent to the product below for acceptable values of x

Answer 1

the answer would be A.

7x × X gives you 7x^2

7x × 2 gives you 14 X

so the answer is the square root of 7x^2 + 14 X

Answer 2

correct option is A)
`\sqrt{7x^(2)+14x}`

Explanation:

provided expression is
`√(7x) *√(x+2)`

since,
`√(m)*√(n)=√(mn)`

`√(7x)*√(x+2)`

`√((7x)*(x)+(7x)*2)`

`\sqrt{7x^(2)+14x}`

Which means correct option is A)
`\sqrt{7x^(2)+14x}`
