Question

Resolve into factor

Answer 1

${a}^{4} - {b}^{4}$

$( {a}^{2} ) {}^{2} - ( {b}^{2} ) {}^{2}$

From the identity,

a^2-b^2 =(a-b)(a+b)

We get,

$( {a}^{2} - b {}^{2} )(a {}^{2} + b {}^{2} )$

Again,

(a-b)(a+b)$( {a}^{2} + b {}^{2} )$

Cheers!!

Answer 2

(a ke square ka square )-(6ke square ka square )

(a ke square +6 ka square )(a ke square -6 ka square )

(a ka square +6 ka square )(a+6)(a-6)
