Question

Factorise
x2 + 11x + 28

Answer 1

`\huge\boxed{(x+7)(x+4)}`

Explanation:

To factor a polynomial expression with a degree of 2, simply look at the second and last term (11x and 28). Discard the x and you are left with 11 and 28.

To factor the equation, simply find two numbers that add to 11, and multiply to 28, 4 and 7. Then, simply use those two numbers to make the terms.

Hope it helps :) and let me know if you want me to elaborate.
