Find the possible values of m if the equation has equal roots. solve the equation ? ?

For to have one root, we need to have the discriminant be 0. Recall that for the general quadratic polynomial,



the discriminant is . In this case,



Solve for when :

What can we do about it

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
