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

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