Answer 1

Step-by-step explanation:

x2 +14x+ 33

we can write this as-

x2+11x+3x+33

taking common ( x from x2 and 11x and 3 from 3x and 33)

x(x + 11)+3(x+11)

taking (x+11)common , we get,

(x+3)(x+11)

other questions can be similarly solved with middle term splitting or algebraic identities.

Answer 2

Answer:

x2 +14x+ 33

we can write this as-

x2+11x+3x+33

taking common ( x from x2 and 11x and 3 from 3x and 33)

x(x + 11)+3(x+11)

taking (x+11)common , we get,

(x+3)(x+11)

other questions can be similarly solved with middle term splitting or algebraic identities.
