Respuesta :

X*2 +5 =41
Subtract 5 from both sides
X*2=36

Square root of 36 is 6

X=6

Solve

6*2+5 =41
This’s correct!

Answer:  The required solution is x = 6,  -6.

Step-by-step explanation:  We are given to solve the following quadratic equation using square roots :

[tex]x^2+5=41~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

To solve a quadratic equation by square root method, we need to take x² term on one side and the constant term on the other. After that, the square root on both the sides are taken.

From equation (i), we have

[tex]x^2+5=41\\\\\Rightarrow x^2=41-5\\\\ \Rightarrow x^2=36\\\\\Rightarrow x=\pm\sqrt{36}~~~~~~~~~~~~\textup{[taking square root on both the sides]}\\\\\Rightarrow x=\pm 6.[/tex]

Thus, the required solution is x = 6,  -6.
