(x+5)(x-5) , You use difference of two squares to do this. Remember that if the sign in the equation was (+) then you wouldn’t be able to continue factoring. You can only factor equations like these if there is a subtraction sign.
The rule is to put them in order
Answer:
total pay in 4 weeks is $ 1960.00
$ 12.25 per hour
Step-by-step explanation:
5 x 165= $ 825
6 x 110= $ 660
5 x 95= $ 475
____________
$ 1960.00 dollars divided by 160 = 12.25
1960/ 160= 12.25
The general formula for a equation of the form:
is:
In this case we notice that a=1, b=-4 and c=3. Plugging this values in the general formula we get:
then:
and
Therefore, x=3 or x=1.
