(y + 8)(y - 7)
If you mean: x squared -x -56 = 0 then using the quadratic equation formula x = 8 or x = -7
4(h2 - 14)
n2 = 10n + 56 Subtract (10n + 56) from each side: n2 - 10n - 56 = 0 Now you have something on the left side that you can factor: (n - 14) (n + 4) = 0 n = +14 n = - 4
85 + 25 - 56 = 54
x2 + 7x - 56 cannot be factorised.
(y + 8)(y - 7)
If you mean: x squared -x -56 = 0 then using the quadratic equation formula x = 8 or x = -7
4(h2 - 14)
n2 = 10n + 56 Subtract (10n + 56) from each side: n2 - 10n - 56 = 0 Now you have something on the left side that you can factor: (n - 14) (n + 4) = 0 n = +14 n = - 4
30 + 50 - 56 + 2306 = 2330
56 + 82 - 9 = 129
85 + 25 - 56 = 54
The expression n2 - n - 56 factors to (n - 8)(n + 7).
23 + 56 - 4 = 75
72 minus the root of squared minus equals 72 but you have to be smart to know that the minimum circumference s 56 there you go
(-9 x -8) + (-16) = (72) -16 = 56
