Answer:
(x-7)(x+4)
Step-by-step explanation:
We have given an expression.
x²-3x-28
We have to factorize given expression.
Split the middle term of above expression so that the sum of two term should be -3 and their product be -28.
x²-7x+4x-28
Making groups and taking common , we have
x(x-7)+4(x-7)
Taking (x-7) as common, we have
(x-7)(x+4) which is the answer.
