Answer 1

Answer:

+-3

Step-by-step explanation:

3x^2=27

x^2=27÷3

x^2=9

Answer 2

Answer:

$\bold{\underline{\underline{\green{ɢɪᴠᴇɴ:-}}}}$

${3x}^{2} = 27$

$\bold{\underline{\underline{\pink{ғɪɴᴅ:-}}}}$

Standard form of quadratic equation.

$\bold{\underline{\underline{\blue{Sᴏʟᴜᴛɪᴏɴ:-}}}}$

${3x}^{2} = 27 \\ {x}^{2} = \frac{27}{3} \\ {x}^{2} = 9 \\ x = \sqrt{9} \\ x = 3$

$\bold{\underline{\underline{\purple{Check:-}}}}$

$3 {(3)}^{2} = 27 \\ 3(9) = 27 \\ 27 = 27$
