Mathematical statements with variables, numbers, and operations
Terms with exactly the same variable parts
(a+b)(c+d)=ac+ad+bc+bd(a + b)(c + d) = ac + ad + bc + bd(a+b)(c+d)=ac+ad+bc+bd
Writing an expression as a product of its factors
a2−b2=(a−b)(a+b)a^2 - b^2 = (a - b)(a + b)a2−b2=(a−b)(a+b)
Expressions with three terms
x=−b±b2−4ac2ax = \frac{-b ± \sqrt{b^2-4ac}}{2a}x=2a−b±b2−4ac
Systems of equations solved together to find satisfying values
Δ=b2−4ac\Delta = b^2 - 4acΔ=b2−4ac
Two distinct real roots
