The formula for the quadratic formula is x (c in this case) = (-b(+/-)√(b²-4ac))/2a
This is used for an equation in standard quadratic form: ax² + bx + c = 0
1.) Put it in the correct form, if not already in it.
Ex. c² + 6c + 8 = 0
2.) Identify each part of the equation:
a = 1 (the leading coefficient), b = 6 (the coefficient in front of the second variable), c = 8
3.) Plug in each variable answer
c = (-6(+/-)√(6²-4(1)(8))/2(1)
4.) Simplify
c = (-6(+/-)√(36-(4*8))/2
c = (-6(+/-)√(36-32))/2
c = (-6(+/-)√(4))/2
c = (-6(+/-)2)/2
*Here, the equation splits in two. It becomes:
c = (-6+2)/2 AND c = (-6-2)/2
*Simplify again:
c = -4/2 AND c = -8/2
c = -2 AND c = -4
The answers c = -2 and c = -4 would solve the given equation.

Answer: 1/20 (fraction) or 0.05 (decimal)
Step-by-step explanation:
first i like to make them a decimal so its easier.
1/4 = 0.25
1/5 = 0.2
multiply 0.25 and 0.2 = 0.05
make 0.05 a fraction
1/20
simplify. (it's already in its simplest form)
the answer is 1/20 as a fraction or 0.05 as a decimal.
(i dont know which one ur teacher wants u to do fraction or decimal?)
Answer:
7/22 as a decimal rounded to the nearest hundredths is 0.32.
Step-by-step explanation:
7/22 as a decimal is .31818181818182,the thousandths place is over 5 which makes the hundredths place .01 higher when rounded, making it 0.32.
