x=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}
x=2a−b±b2−4ac
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

The solution is n= <u>+</u> 4i/√11
Step-by-step explanation:
step 1: 10n^2+n^2+16=0
step 2: 11n^2+16=0
step 3: 11n^2= -16
step 4: n^2= -16/11
step 5: taking square root on both sides,
n= √(-16)/√11 (square root of a negative number is a <u>complex term</u> 'i')
n= <u>+</u> 4i/√11
Answer:
It is because the red disks were more than the other disks before the pupils added other disks.
Difference would be that is a diameter is double a radius and a radius is half of a diameter.
A similarity would be that they would are within a circle and touch the center of circle
