factor n^2+11n+28

factor

n^{2} + 11 n + 28

(n + 4) (n + 7)

Solution steps

n^{2} + 11 n + 28

Break the expression into groups

= (n^{2} + 4 n) + (7 n + 28)

Factor out

n

from

n^{2} + 4 n : n (n + 4)

Factor out

7

from

7 n + 28 : 7 (n + 4)

= n (n + 4) + 7 (n + 4)

Factor out common term

n + 4

= (n + 4) (n + 7)

- 4.9 \cdot t^{2} + 41.67 \cdot t + 60 = 0

- 11 x^{2} + 26 x + 61 = 0

\frac{8 x + 4}{15} = \frac{9 x + 7}{7} - 6

∣ x - 5 ∣ \leq 4

(8.8 - x)^{2} = 8. 8^{2} - x^{2}
