51

Step-by-step explanation:

11+(-7)^2-9 - original

11+49-9 - square the -7, since its in brackets the negative applies too and a negative x a negative = positive, so it ends up as 7x7+49

60-9 - add both positives 11+49=60

51 - subtract 9 from 60, 60-9=51

If 2 and 5 are roots, then (x - 2) and (x - 5) are factors.

f(x) = 4(x - 2)(x - 5)               FOIL

f(x) = 4(x2 - 7x + 10)             distribute

f(x) = 4x2 - 28x + 40
