Question

math anxiety

Answer 1

First of all math is hard and we’ve got to acknowledge that. Also people sometimes take more time to learn some topics while they could excel is others.

My advice would be to look at solved exercises of the kinds of problems you’re struggling with. Most books provide them but if not youtube is your friend, there are lots of excellent teachers there.

Answer 2

Best to learn from khan academy, they make the topic simpler

Answer 3

Great suggestion to practise problems that you have full solutions for.   Hopefully, these will become easier.  
Was the last topic in math easier, or is every chapter the same - causing stress and anxiety?   If so, you may want to discuss this with your guidance teacher.  Math is tough; no one should have to stress to the point of crying over it.  (imho)

Answer 4

It may be your math background is weak; quadratics involves a fair bit of algebraic understanding, if you’re missing that, you’re going to struggle with a topic built on that concept. Make sure your foundational knowledge doesn’t have gaps.

If you get stuck on a given step, figure out why — is it a problem with understanding quadratics, or a problem understanding algebra, or factoring, or even just addition? This will give you an idea of what other areas of math you need to brush up on.
