If you failed a math test, what are 2 things that you can do to prevent your careless errors?​

1) use a calculator

2) use desmos which is an online graphing calculator (trust me it will help you)

3) Do lots of practice (I know that you probably don't like to practice, but if you practice then you will prevent lots of careless errors because you will have more experience)

4) Pay attention to your teacher

5) When taking a test, try to avoid all distractions and focus on your test.

For me, it really helps to go back and see what i got wrong, check where i made the mistake and solve it again. I think you need to know the basic concept before moving on since math builds on itself. If you have a teacher i think it would really help if you talk to them too, they may have some good tips to help you :)

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
