Solve using factoring: 3x^2+7x+2=0
a=3 , b=7 , c=2 First, write out two sets of paranthesis. Give yourself enough space to write some numbers inside of them. Ex: ( )( ) Second,put x's in both parathesis Ex: ( x )( x ) Third, think about the factors of 3. Only 3 and 1 multiply to get 3. So place 3 in front of the first x and 1 in front of the second x. Ex: (3x )(1x ) Fourth, think about the factors of 2. Only 2 and 1 multiply to get 2. So this is where guessing and checking comes into play. What does 3 multiplied by 2 equal? It equals 6, so place the 2 behind the x in the second set of parathesis, but leave space for either an addition or subtraction sign. Then, you will put 1 behind the x in the first set of parathesis and leave space between. Ex: (3x 1)(1x 2) Now you will determine what the signs should be. For this, look at the original equation. There are two addition signs, so you will put addition signs in both. This changes based on different problems. Ex:(3x+1)(1x+2) The last step involved multiplying the outside terms and adding them to the inside terms since both signs are addition. Ex: 3x*2=6x 1x*1=1x Add the 6x+1x and you will get 7x Your answer should be the same number as the middle term in your original equation.
