Do you mean quadratic? Use the formula and plug in the coeff of the x^2 for a, the coeff of the x term for b and the coeff of the constant term for c. 2x^2+13x=4 ---> 2x^2+13x-4 2x^2--->a=2 13x------>b=13 -4---->c=-4

-b + or - sqrt(b^2-4ac) all divided by 2a

Hold on i have chocies
anonymous
  • anonymous
it would be better to say plus and minus, you get two answers
anonymous
  • anonymous
they should both work as solutions to the equation
anonymous
  • anonymous
If you're doing homework they probably want both answers.

A.) x= 13+√201 -------------- 2 B.)x=-13+√177 ---------------- 4 C.) x= -13+√ 201 ---------------- 2 D.) x= -13 +√ 201 ----------- 4

AND + HAS a line under it \[\pm\]

Close, not quite.

substitute your values in the quadratic formula and see which is the correct one.
anonymous
  • anonymous
B?
anonymous
  • anonymous
what's the difference between C and D
anonymous
  • anonymous
no.
anonymous
  • anonymous
c has a 2 and d has a 4
anonymous
  • anonymous
Well the answer is exactly the same as D, only it's + and - sqrt201

  • anonymous
katie, there is no point guessing the answer. take some time and substitute your vlues into the quadratic equation. that will give you the correct answer.
anonymous
  • anonymous
so its D?
anonymous
  • anonymous
If the + is a + - line thing, yes
anonymous
  • anonymous
±
anonymous
  • anonymous
yes it has this \[\pm\] under it so its D
anonymous
  • anonymous
Yeah, i mean it's exactly the same as the formula, it just matters that you plug in the right numbers.
