Solve -4x^2-3+4+3-5y^2+3y^2-5y^2

$$- 4 x ^ { 2 } - 3 + 4 + 3 - 5 y ^ { 2 } + 3 y ^ { 2 } - 5 y ^ { 2 }$$

Evaluate

$$4-7y^{2}-4x^{2}$$

Solution Steps

Add -3 and 4 to get 1.

$$-4x^{2}+1+3-5y^{2}+3y^{2}-5y^{2}$$

Add 1 and 3 to get 4.

$$-4x^{2}+4-5y^{2}+3y^{2}-5y^{2}$$

Combine -5y^{2} and 3y^{2} to get -2y^{2}.

$$-4x^{2}+4-2y^{2}-5y^{2}$$

Combine -2y^{2} and -5y^{2} to get -7y^{2}.

$$-4x^{2}+4-7y^{2}$$

Differentiate w.r.t. x

$$-8x$$
