Question

factorise :-
1. 49l² – x 4 + 8x²y² -16y⁴
2. X
2²– 16x + 63
3. 11x²– 54x + 63
4. 7x -6 – 2x²
5. X
²+ 22x - 48​

Answer 1

Step-by-step explanation:

5.x²+22x-48

x²+24x-2x-48

x(x+24)-2(x+24)

(x-2)(x+24)

2.x²-16x+63

x²-9x-7x+63

x(x-9)-7(x-9)

(x-7)(x-9)

4.-2x²+7x-6

-2x²+3x+4x-6

-x(2x-3)+2(2x-3)

(-x+2)(2x-3)
