Solve (x +9)2 = 25.
alexandr1967 [171]

Answer:

x =  - 4 \: or \: x =  - 14

Step-by-step explanation:

We have been given the equation

(x + 9) {}^{2}  = 25

and we are asked to apply the square root property of equality to our given a equation and isolate the variable

First, take the square root of both sides of our equation

\sqrt{(x + 9) {}^{2} }  =  \sqrt{25}

x + 9 =  \: 15

x + 9 = 5 \: or \: x + 9 =  - 5

x + 9 - 9 = 5 - 9 \: or \: x + 9 - 9 =  - 5 - 9

x =  - 4 \: or \: x =  - 14

<em>THEREFORE, THERE ARE TWO SOLUTIONS FOR OUR GIVEN EQUATION</em>

<em>x + 9 = 5 \: then \: x =  - 4. \\ x + 9 =  - 5 \: then \: x =  - 14</em>

<u><em>PLEASE</em><em> </em><em>MAKR</em><em> </em><em>ME</em><em> </em><em>BRAINLIEST</em><em> </em><em>IF</em><em> </em><em>YOU</em><em> </em><em>ARE</em><em> </em><em>HAPPY</em><em> </em><em>WITH</em><em> </em><em>THE</em><em> </em><em>ANSWER</em></u>
