Solve -0,1*(2x^2+6)(5-4x^2)

$$- 0,1 \times ( 2 x ^ { 2 } + 6 ) ( 5 - 4 x ^ { 2 } )$$

Evaluate

$$\frac{4x^{4}}{5}+\frac{7x^{2}}{5}-3$$

Solution Steps

Use the distributive property to multiply -0,1 by 2x^{2}+6.

$$\left(-0,2x^{2}-0,6\right)\left(5-4x^{2}\right)$$

Use the distributive property to multiply -0,2x^{2}-0,6 by 5-4x^{2} and combine like terms.

$$1,4x^{2}+0,8x^{4}-3$$

Expand

$$\frac{4x^{4}}{5}+\frac{7x^{2}}{5}-3$$

Solution Steps
