Ok let's do this*pops knuckles*
let's add the first side
order of operations demands that we do multiplication first(P.E.M.D.A.S)
so
now we can add the 1 from
into our six
now we substract
now we have
now we focus on the
other side
since 5 is in paranthesis we use something called the distributive property. it mean we will multiply the 5 by both of the 2.
now we have
(the three is from the original equation)
now we plug in our final numbers
or
I hope this helps

Answer:
Step-by-step explanation:
Vertex form of a quadratic equation;
Vertex of the parabolas (h, k)
The vertex of the parabola is either the minimum or maximum of the parabola. The axis of symmetry goes through the x-coordinate of the vertex, hence h = -3. The minimum of the parabola is the y-coordinate of the vertex, so k= 7. Now substitute it into the formula;
Now substitute in the given point; ( -1, 9) and solve for a;
Hence the equation in vertex form is;
In standard form it is;
