Question 1104204
<br>
If the function has a minimum value when x=-1.5, then x=-1.5 is the axis of symmetry.<b>
Then if the distance between the two zeros is 9, the two zeros are 9/2=4.5 units either side of the axis of symmetry; so the two zeros are -6 and +3.<br>
I'm guessing that is what the first question was supposed to be asking:
a. The two roots are -6 and 3.<br>
Since the two roots are -6 and 3, the equation is
{{{y = (x+6)(x-3) = x^2+3x-18}}}
so<br>
b. q=3; r = -18
