Question

(iii) (√2a+√3b)² plz solve it plz ​

Answer 1

USING THE IDENTITY -

(a+b)²= a² + 2ab + b²

=(√2a)² + 2×√2a×√3b + (√3b)²

=2a² + 2√6ab + 3b²

Answer 2

$= ( \sqrt{2a} + \sqrt{3b} )² \\ \\ = ( \sqrt{2a} ) {}^{2} + ( \sqrt{3b} ) {}^{2} + 2 \times \sqrt{2a} \times \sqrt{3b} \\ \\ = 2a + 3b + 2 \sqrt{6ab}$
