Solving Quadratic Equations By Factoring Worksheet Answers 19 If a quadratic equation can be factored and each factor contains only real numbers then there cannot be an imaginary solution True 20 If a quadratic equation cannot be factored then it will have at least one imaginary solution False Example x2 10 2 Create your own worksheets like this one with Infinite Algebra 2 Free trial
To solve quadratic equations by factoring we must make use of the zero factor property Factoring Method Set the equation equal to zero that is get all the nonzero terms on one side of the equal sign and 0 on the other Answer x dfrac 2 9 dfrac 3 7 Exercises For the following problems solve the equations if possible Solving by factoring Suppose we want to solve the equation x 2 3 x 10 0 then all we have to do is factor x 2 3 x 10 and solve like before x 2 3 x 10 can be factored as x 2 x 5 Show me the factorization The complete solution of the equation would go as follows x 2 3 x 10 0 x 2 x

It s the formula for finding the solutions to the quadratic What he is saying is you need 2 numbers that when added together equal 2 but when multiplied equals 35 Note since the multiplied is negative one of the two numbers will be negative and the other will be positive 2 comments Here is the complete solution You should back substitute to verify that latex x 0 latex latex x 3 latex and latex x 3 latex are the correct solutions Example 5 Solve the quadratic equation below using the Factoring Method The first thing I realize in this problem is that one side of the equation doesn t contain zero
A quadratic equation is an equation involving the square of a number which is the highest power in the equation It is usually in the standard form ax 2 bx c 0 where a b and c are numbers and x is an unknown The variable a cannot be 0 but b and c can be 0 Note that the operations can be or In order to use the Zero Product Property the quadratic equation must be factored with zero on one side So we be sure to start with the quadratic equation in standard form a x 2 b x c 0 Then we factor the expression on the left Exercise 4 1 13 Solve x 2 2 x 8 0
