Question

One of the factors of g2 – 28g + 196 is:
Answer
g – 14
g + 14
g – 7
g + 7

Answer 1

the first one

Answer 2

g-14

Answer 3

To factorise simple polynomials such as this, find a pair of numbers which produce the final term (196) and sum to the second term (-28). -14 and -14 result in this, thus the factorised form is (g-14)(g-14).
