Solve (n^{1}-1,6b^{2}+0,9x^2)-10,8a^2-b^2+1,7c^2

$$( n ^ { 1 } - 1,6 b ^ { 2 } + 0,9 x ^ { 2 } ) - 10,8 a ^ { 2 } - b ^ { 2 } + 1,7 c ^ { 2 }$$

Evaluate

$$\frac{9x^{2}}{10}+\frac{17c^{2}}{10}-\frac{13b^{2}}{5}-\frac{54a^{2}}{5}+n$$

Solution Steps

Calculate n to the power of 1 and get n.

$$n-1,6b^{2}+0,9x^{2}-10,8a^{2}-b^{2}+1,7c^{2}$$

Combine -1,6b^{2} and -b^{2} to get -2,6b^{2}.

$$n-2,6b^{2}+0,9x^{2}-10,8a^{2}+1,7c^{2}$$

Differentiate w.r.t. x

$$\frac{9x}{5}$$
