Hello
So here's a question, from a paper (unit 3 edexcel)

Solve 5x2 – 3x – 7 = 0

Give your solutions correct to 3 significant figures.

The answers from the mark scheme are: 1.52 & -0.921

however when I use the quadratic formula, I cant seem to get this answer!
2. Re: Simple Quadratic Formula Q.?
A is 5, B is -3, C is -7. Plug those into the formula.
