Question

factorize :

(1)x²+x-72.

(2)p²-7p-120.

(3) 16-17z+z²

(4) a²+5a-104.

(5)3x²+11x+10​

Answer 1

Answer:-

Solution 1:-

Step-by-step explanation:

= x²+x-72

= x²-9+8X-72

= x (x-9) +8(X-9)

= (x+8)(x-9)

= x+8=0

= x-9=0

= x=9 Ans..

Solution 2:-

= p²-7p-120

= p²-15p+8p-120

= p(p-15)+8(p-15)

= (p-15)(p+8)
