How to solve quadratic equations pdf
WebFeb 27, 2024 · A standard form of quadratic equation in one variable can be solved by factorising the equation, i.e., by making factors out of the equation. Consider the equation x 2 − 7 x + 12 = 0 , it can also be written as (x-3) (x-4)=0. Now this factorised equation can be very easily solved using a property of real numbers called the zero-product rule. WebAug 13, 2024 · Solve x2 − 6x + 8 < 0 graphically. Write the solution in interval notation. Solution: Step 1: Write the quadratic inequality in standard form. The inequality is in standard form. x2 − 6x + 8 < 0. Step 2: Graph the function f(x) = ax2 + bx + c using properties or transformations. We will graph using the properties.
