Chemical equations are the symbolic representations of chemical reactions that are made up of reactants and products. It is made up of the chemical formulas of the reactants and the chemical formula of the products. The reactants are the substances or chemicals that takes part in during a reaction and the products are the chemicals are the substances that result from the chemical reaction. Reactants are on the left side of the chemical equation and the products are on the right side of the chemical

Solving the quadratic equations using the FOIL method makes the equations easier for me to understand. The Foil method‚ multiplying the First‚ Outer‚ Inner and Last numbers‚ breaks down the equation a little further so you understand where some of your numbers are coming from‚ plus it helps me to check my work. Equation (a.) x^2 – 2x – 13 = 0 X^2 – 2x = 13 (step a) 4x^2 – 8x = 52 (step b‚ multiply by 4) 4x^2 – 8x + 4 = 52 + 4 (step c‚ add to both sides the square of original
