Hey mate.....

9 {x}^{4} - ( {x}^{2} + 2x + 1)

the ....... which is in brackets can be solved using( a + b) ^ whole square formula ..

9 {x}^{4} - ( {x }^{2} + {1}^{2} + 2(x)(1)

9 {x}^{4} - (x + 1)(x + 1)

9x^4 - (x+1 ) ^2

now u should use a^ - b^ formula....

(3x^)^2 - (x+1)^

(3x^2 - (x+1) ) ( 3x^2 + ( x+1))

hope it helps uu dear. . . . . . ☺☺
