Question

I don't know how to solve this question could you guys please help me solve it​

Answer 1

∆ Answer ∆

:⟹ X⁴ - ( X - Z )⁴ = (X²)² - [ ( X - Z)² ]²

:⟹ X⁴ - ( X - Z )⁴ = X⁴ - ( X - Z ) ⁴

:⟹ X⁴ - ( X - Z )⁴ - X⁴ + ( X - Z )⁴

:⟹ = 0 { Because of [ X⁴ - X⁴ = 0 , - ( X - Z )⁴ + ( X - Z )⁴= 0 ] )

I hope it helps you

Step-by-step explanation:

${x}^{4} - (x - z) {}^{4} \\ \\ = ( {x}^{2} ) {}^{2} - [(x - z) {}^{2} ] {}^{2} \\ \\ = [ {x}^{2} + (x - z) {}^{2}][{x}^{2} - (x - z) {}^{2} ] \\ \\ = ({x}^{2} + {x}^{2} - 2xz + z {}^{2} )(x + x - z)(x - x + z) \\ \\ =( 2 {x}^{2} - 2xz + z {}^{2}) (2x - z)(z)$
