Question

Which of the following is equivalent to the radical expression below when
x>=2?
(√x-2)(√x+9)

Answer 1

The equivalent expression of $(\sqrt x - 2)(\sqrt x + 9)$ is $x + 7\sqrt x - 18$

How to determine the equivalent equation?

The expression is given as:

$(\sqrt x - 2)(\sqrt x + 9)$

Expand the expression

$x - 2\sqrt x + 9\sqrt x - 18$

Evaluate the like terms

$x + 7\sqrt x - 18$

Hence, the equivalent expression of $(\sqrt x - 2)(\sqrt x + 9)$ is $x + 7\sqrt x - 18$
