Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7
For a you need to do (10 times 13) plus (10 times 7) because there's two boxes one is shaded.
For b you need to do (7.5 times 20) plus (2.5 times 20)
