The quadratic equation

This is followed by an equation on the next line which reads "the sum from i = 0 to 2 a subscript i x superscript i equals 0". This is then followed by the line:

has solutions given by

This line is followed by another equation which reads "x equals (minus a subscript 1 plus or minus the square root of (a subscript 1 squared minus 4 times a subscript 2 times a subscript 0)) divided by (2 times a subscript 2)".

The quadratic equation
Σ_i=0² a_i xⁱ = 0
has solutions given by
x = (-a₁ ± √(a₁² - 4 a₂a₀)) / (2 a₂)
