Question 983097

Which value of C in the equation y = x2 - 5x + C will provide zeros at x = -1 and x = 6?

 
   C = -6 
   C = -1 
   C = 1 
   C = 6 
<pre>{{{y = x^2 - 5x + C}}}
Product of roots = {{{c/a}}}
Also, product of roots = - 1(6), or - 6
Therefore, {{{c/a = - 6}}}, or {{{c/1 = - 6}}}, or {{{highlight_green(C = - 6)}}}
