sorry it also says "the graph of each function has its vertex on the x-axis. it asks to find both values of q... soryy and thanks!!

amistre64 · Answer

4x^2-qx+25  would have to be a perfect square trinomial

amistre64 · Answer

if you know hoe to find a determinant of a quadratic, the rest is to set it to 0

amistre64 · Answer

q^2 -4(4)(25) = 0 will give you vales for q that make it a perfect square trinomial

;)  good luck
