Hey, I'm in Grade 11 Functions and I've got a question that I'm kinda stuck on. The question is above. I'm pretty sure you need to partially factor this equation but after that, I'm honestly not sure what to do.
Here's what I tried out so far (don't bully me ): So 2x^2-7x+c can be partially factored to get x(2x-7)+c=0. The roots here are like x=0 and x=7/2. Do I need to substitute -1/2 for one of the roots, or do I need to like substitute one x value with -1/2, or?
That's all I know, If anyone could help me out?
