Question

(√2x+3)(√2x+3)
Please answer step by step

Answer 1

Answer:

11 + root2

Step-by-step explanation:

a^2 + b^2 + 2ab

(root 2)^2 + (3)^2 + 2(root 2)(3)

2+9+6 root2

11+ root 2

Answer 2

Answer:

Step-by-step explanation:

(√2x+3)(√2x+3)   [a+b][a+b]=[a+b]²

a=√2x

b=3

therefore(√2x+3)²    [a+b]²=a²+2ab+b²

=>(√2x)²+2(√2x)(3)+3²

=>2x+6(√2x)+9
