1) 9a²-16b²( a²-b²) = (a+b)(a-b)= (9a+16b)(9a-16b)
2)x⁴-y⁴= (a²-b²)²= (x²-y²)²= (x²+y²)(x²-y²)= (x²+y²)(X+y)(x-y)
3) x⁴-81= (x⁴-3⁴) = (x²)²-(3²)²..... now u can solve by taking help of above....
4)2x-32x⁵= 2x(1-16x⁴) = 2x[1⁴-(2x⁴)] =.... now u can solve this by understanding above ....
5) (a-b)² this will be solved by this.....
= [(2a)²-2×2a×1+1 ] = (2a-1)²= (2a-1)(2a-1 hope u can do now....
if not please send me the message I will solve all.....
