how+to+factor+when+a=1

To factor an equation where a=1 make sure it is in the format of x2+bX+c or standard form. Next you will check for a gcf If the gcf is any number or variable other than one then you put it out outside of the equation. You then set up two parentheses with an X in each. (X) (X) Then you determine whether to use a subtraction sign or a plus sign This is determined by signs in the equation 1. If the equation is in form X2+bX+c, then you have two addition signs 2. If the equation is in form X2-bX+c, then you have two subtraction signs 3. If the equation is in form X2-bX-c, then you have one subtraction and one addition sign. The larger factor will have the negative 4. If the equation is in form X2+bX-c, then you have one addition and one subtraction sign. The larger number will be positive

Once you have your equation started you should factor out the constant or C. You will then plug in the pairs of factors until an answer is found. =Example 1= X 2 +7X+12 (x )(x ) 1,2,3,4,6,12 (x+3)(x+4)
