For using the factorisation method, the quadratic equation should be in descending order. It is already given in descending order. Similarly, all the terms in the left-hand side of the equation and there is no term in the right hand side of the equation. So, we can start the process for factoring the quadratic equation to solve it. The trinomial in the quadratic expression is expanded as a quadrinomial. There is a factor in every two terms commonly in the quadrinomial.

A proportion is a statement that two ratios are equal. Remember that when we multiply a whole number by a fraction, we use the rule We are now ready to solve an equation involving fractions. Note that the division rule allows us to divide each term of an equation by any nonzero number and the resulting equation is equivalent to the original equation. Example 5. Errors are sometimes made in very simple situations. An identity is true for all values of the literal and arithmetic numbers in it. Once you've done that, refresh this page to start using Wolfram Alpha. Solution Even though this equation can easily be solved mentally, we wish to illustrate the subtraction rule. Toggle navigation GetEasySolution. We next apply the division rule. Always check in the original equation. Example 12 Two sons were to divide an inheritance in the ratio of 3 to 5.

To prepare to use the division rule for solving equations we must make note of the following process:. Remember that when we multiply a whole number by a fraction, we use the rule We are now ready to solve an equation involving fractions. Again, be careful in setting up the proportion. The literal numbers in an equation are sometimes referred to as variables. Thus, we will write the ratio of 3 to 4 as. Toggle navigation GetEasySolution. Keeping in mind our goal of obtaining x alone, we observe that since 3 has been subtracted from 2x, we add 3 to both sides of the equation. If we choose to first add 2x to both sides, we obtain We now add 2 to both sides. There is no mandatory process for solving equations involving more than one rule, but experience has shown that the following order gives a smoother, more mistake-free procedure. We now look at a solution that requires the use of both the subtraction rule and the division rule.

In the example we need to multiply by a number that is divided by 3. We must think of eliminating the number 2 from the left side of the equation and also the lx from the right side to obtain x alone on one side. Example 4 Solve for x: 0.
