Answer:
![-\frac{1}{2}x^2-2x-5 [\tex]Step-by-step explanation:To convert it to standard form, all you need to do is expand the square and simplify. This would get us to: [tex]-\frac{1}{2}(x^2 + 4x + 4) - 3](https://tex.z-dn.net/?f=%20-%5Cfrac%7B1%7D%7B2%7Dx%5E2-2x-5%20%5B%5Ctex%5D%3C%2Fp%3E%3Cp%3E%3Cstrong%3EStep-by-step%20explanation%3A%3C%2Fstrong%3E%3C%2Fp%3E%3Cp%3ETo%20convert%20it%20to%20standard%20form%2C%20all%20you%20need%20to%20do%20is%20expand%20the%20square%20and%20simplify.%20This%20would%20get%20us%20to%3A%20%5Btex%5D-%5Cfrac%7B1%7D%7B2%7D%28x%5E2%20%2B%204x%20%2B%204%29%20-%203)
which simplifies further to 
and combine the -2 and -3 to get [tex] -\frac{1}{2}x^2-2x-5 [\tex]
Hope this helps :)
Hello
14-4x=2y divide 2 to both sides VVVVV7-2x=y you will need this on the next step-----------------------------------------------------y+2x=7y=7-2x(7-2x)+2x=7 -------> 7-2x+2x=7 7=7Have a nice day
