Hi!
<u>Explanation: </u><u><em>This question is about math, and this lesson is about order of operations. I will give you a hint. You had to used PEMDAS, P-Parenthesis should be go first, E-Exponents, M-Multiply, D-Divide, A-Add, and S-Subtract. If you use multiply, divide, add, or subtract it should go left to right. First, you had to multiply and divide should go left to right. And it gave us -15+10. And finally, you should add and subtract by left to right. And it gave us -5 is correct answer. Hope this helps! Thank you for posting your question at here on Brainly. And have a great day. -Charlie</em></u>

Answer:
Ok, we know that we have a parabola (a quadratic equation) that is concave down.
This means that the "arms" of the graph will go down, then, the vertex is the maximum of the parabola.
Now we know that the vertex (again, the maximum) is on the third quadrant, this quadrant is on the negative region of x and on the negative region of y.
So, if from this point the arms of the parabola go down, then the arms will never intersect the x-axis.
So we do not have x-axis intercepts, which means that this parabola as no real roots.
And a parabola has always a y-intercept, but we have no enough information to conclude which is the y-intercept.
