The square of( $x+\frac{5}{2}$) is $\frac{25}{4}$.What is $x$?

• A. 1
• B. -5
• C. 5/2
• D. 3

Answer 1

The correct option is B

-5

$\Rightarrow$$(x+5/2{)}^2$= $\frac{25}{4}$
$\Rightarrow$($x$ + $\frac{5}{2}$) = $\pm$$\frac{5}{2}$ (Taking square root on both sides)
$\Rightarrow$($x$ = 0 or ($x$= -5
