Question

simplify (√2x+√3y) (√5-√2b) ​

Answer 1

Answer:

Here we consider a = (√2x+√3y) and b= (√2x-√3y).

Using formula

{(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2}(a+b)

2

=a

2

+2ab+b

2

(√2x + √3y)² + 2(√2x+ √3y)(√2x - √3y)+(√2x-√3y)²

={(√2x+√3y)+(√2x-√3y)}²

={2√2x}²

=4 x 2x²

=8x²

hope my answer will help you

Answer 2

(√2x+√3y) (√5-√2b) ​

√2x (√5-√2b) +√3y (√5-√2b)

√10x - 4bx + √15y - √6by
