x^2 - 5x - 14
To factor
Look for all the factors of '14' / They are 1,2,7,& 14.
Of these factorts we need to select two numbers ,which added or subtracted com to '5'.
The numbers are .2. & .7.
Hence write up the brackets
(x 2 )(x 7)
Next ; to select the correct signs.
We note that '14' is negative, so the two signs are different ; + & - . Where does the '+' & '-'- go . Since '5x' is minus(-) then the large number in the brackets is the minus(-).
Hence
( x + 2)(x - 7) Done!!!!
-(x - 7)(x + 2)
x2+5x-14 = (x+7)(x-2) when factored
x2-5x-36 = (x-9(x+4) when factored
x - 3
x2 - 5x - 66 is a quadratic expression that factors out to (x - 11)(x + 6)
x2 + 5x - 120 can not be factored.
-(x - 7)(x + 2)
x2+5x-14 = (x+7)(x-2) when factored
When factored it is: (x-9)(x+4)
x -9
which of the following is a factor of x2 - 5x - 6
(x - 2)(x - 3)
x2+5x-6 = (x+6)(x-1) when factored
x2-5x+4 = (x-1)(x-4) when factored
x2+5x+6 = (x+2)(x+3)
x2-5x-36 = (x-9(x+4) when factored
5(x2 + x + 1)
