Step 1. <span>Gather like terms
</span>
![7-(-5x*x)-10,4x ](https://tex.z-dn.net/?f=7-%28-5x%2Ax%29-10%2C4x%0A)
<span>
Step 2. </span><span>Use </span>Product Rule:
![x^{a} x^{b} = x^{a+b}](https://tex.z-dn.net/?f=%20x%5E%7Ba%7D%20%20x%5E%7Bb%7D%20%3D%20x%5E%7Ba%2Bb%7D%20)
![7-(5 x^{2} )-10,4x](https://tex.z-dn.net/?f=7-%285%20x%5E%7B2%7D%20%29-10%2C4x)
Step 3. Simplify brackets
![7+5 x^{2} -10,4x](https://tex.z-dn.net/?f=7%2B5%20x%5E%7B2%7D%20-10%2C4x)
Step 4. Simplify
![7+5 x^{2} -10](https://tex.z-dn.net/?f=7%2B5%20x%5E%7B2%7D%20-10)
to
![5x^{2} -3](https://tex.z-dn.net/?f=%205x%5E%7B2%7D%20-3)
![5 x^{2} -3,4x](https://tex.z-dn.net/?f=5%20x%5E%7B2%7D%20-3%2C4x)
