 Given \: ( 2x + 3 )^{2} = 25

 \implies ( 2x + 3 )^{2} = 5^{2}

 \implies ( 2x + 3 )= \pm \sqrt{5^{2}}

 \implies 2x + 3 = \pm 5

 \implies 2x = \pm 5 - 3

 \implies x = \frac{\pm 5 - 3 }{2 }

 \implies x = \frac{5-3}{2} \:Or \: x = \frac{-5-3}{2}

 \implies x = \frac{2}{2} \:Or \: x = \frac{-8}{2}

 \implies x =  1 \:Or \: x = -4

Therefore.,

 \green { x = 1 \: Or \:x = -4 }
