(b) 9x²-1 =(3x+1)(3x-1) (Answer) {Since we know the formula (a²-b²) =(a+b)(a-b)}

(c) x²+8x+15 = x² +3x+5x+15 =(x+3)(x+5) (Answer)

(d) 4x²+16x+15 =4x²+10x+6x+15 = 2x(2x+5) +3(2x+5) =(2x+5)(2x+3) (Answer)

(e) x²-y² =(x+y)(x-y) (Answer)

(f) x^{4}-y^{4} =(x^{2}   +y^{2})(x^{2}  -y^{2})=(x^{2}  +y^{2})(x+y)(x-y) (Answer) {Since we know the formula (a²-b²) =(a+b)(a-b)}
