Re-write the quadratic function below in Standard Form y= y= \,\,-(x+8)^2+7 −(x+8) 2 +7

Answer 1

Above equation is really confusing. I think quation is y=-(x+8)^2+7 changing in standard form.

We know perfect square formula: ( a+b)^2= a^2 + 2ab +b^2 so we will use this formula for (x+8)^2= x^2+16x+64

Y= -(x+8)^2+7= -( x^2+16x+64)+7

Y = - x^2-16x-64+7

Y = -x^2-16x-57 this is quadratic equation in standard form.

Answer 2

I'm assuming y=-(x+8)²+7 is the equation since the above equation is confusing.

The problem is wanting the form, y = ax²+bx+c

-(x²+16x+64)+7 = -x²-16x-64+7 = -x²-16x-57

y = -x²-16x-57
