Question

x^4-(x-z)^2 solve the question

Answer 1

Using identity

a²-b²= (a+b)(a-b)

= (x²)²- (x-z)²
= (x²- (x-z))(x²+ (x+z))
= (x²-x+z)(x²+x+z)
or
= x⁴-( x²+z²-2xz)
= x⁴-x²-z²+2xz

Formula to be used
=-=-=-=-=-=-=-=-=-=-=-=
$= > { \alpha }^{2} - { \beta }^{2} = ( \alpha + \beta )( \alpha - \beta )$
