Ex 14.2, 4 Factorise. (iv) 𝑥^4 – 〖"(x – z)" 〗^4 𝑥^4 – 〖"(x – z)" 〗^4 = 〖(𝑥^2)〗^2 − [(𝑥 − z)^2 ]^2 Using 𝑎^2 − 𝑏^2 = (a + b) (a − b) Here 𝑎=𝑥^2 and b = (𝑥 − z)^2 = [𝑥^2+(𝑥 − z)^2 ] [𝑥^2 −(𝑥 − z)^2] Asking Using 𝑎^2 − 𝑏^2 = (a + b) (a − b) Here 𝑎=𝑥 and b = (𝑥 − z) Asking Using 𝑎^2 − 𝑏^2 = (a + b) (a − b) Here 𝑎=𝑥 and b = (𝑥 − z) = [𝑥^2+(𝑥 − z)^2 ] [2𝑥− z] [𝑧] Using 𝑎^2 − 𝑏^2 = 𝑎^2+𝑏^2 − 2ab Here 𝑎=𝑥 and b = 𝑧 Using 𝑎^2 − 𝑏^2 = 𝑎^2+𝑏^2 − 2ab Here 𝑎=𝑥 and b = 𝑧
