simplify (2n^2-5n-6)+(-n^2-3n+11)

simplify

(2 n^{2} - 5 n - 6) + (- n^{2} - 3 n + 11)

n^{2} - 8 n + 5

Solution steps

(2 n^{2} - 5 n - 6) + (- n^{2} - 3 n + 11)

Simplify

(2 n^{2} - 5 n - 6) + (- n^{2} - 3 n + 11) : 2 n^{2} - 5 n - 6 - n^{2} - 3 n + 11

= 2 n^{2} - 5 n - 6 - n^{2} - 3 n + 11

= 2 n^{2} - n^{2} - 5 n - 3 n - 6 + 11

Add similar elements:

2 n^{2} - n^{2} = n^{2}

= n^{2} - 5 n - 3 n - 6 + 11

Add similar elements:

- 5 n - 3 n = - 8 n

= n^{2} - 8 n - 6 + 11

Add the numbers:

- 6 + 11 = 5

= n^{2} - 8 n + 5

0 = x^{2} + 6 x - 7

d^{2} + d - 7 = - 5

\frac{1}{2} (2)

8 x - x^{2} = 15

1 5^{\frac{3}{2}}
