y = a(x + r 1)(x + r 2) where a is a known constant, r 1 and r 2 are roots of the equation (x intercepts), and x and y are variables. Each of the forms looks drastically different
If a quadratic equation is given, substitute x = 0 x = 0 and solve for y y to get the y y intercept. Finding the y y -Intercept – Example 1: Find the y y -intercept of the equation y =
Explain mathematic equations
Mathematical equations are a way of representing mathematical relationships between variables. By solving an equation, we can find the value of a variable that is unknown.
