Answer 1

Answer:

option c

Step-by-step explanation:

Given:- √2x^2+√9=9

•To find:- the value of x

• Solution:- According to the question,we have to determine the value of x

and the equation is

√2x² + √9 = 9

or,√2x² + 3 = 9

or,√2x= 9-3

or,2x² = 36

or,x²= 18= (3√2)²

so, x = 3√2, -3√2

so the value of x is 3√2 and -3√2
