To factor this collect the like terms..2y would go with -7y to make -5y etc. Then factor the expression by factoring out 9 Your final answer should be 9(1-y+x^2)
If you need to simplify this calculate the sum or difference between numbers (3-1+7=9)
Your final answer for this should be 9-9y+9x^2
Hope this helps!

Answer:
vertex is at (0,0)
Step-by-step explanation:
Find the vertex of the parabola y = 8x2.
I assume you meant y = 8* x^2
this can be compared to the general vertex form y = a (x - h)^2 + k
where vertex at (h, k)
so then...
h =0 and k = 0 here
vertex is at (0,0)
Answer: The answer is -19.5
Step-by-step explanation: This is because 1/2 is .5 in decimal form. A negative <em>PLUS </em>a positive = is negative since the <em>-20 i</em>s larger than .5
