oWrite your birth date or the birth date of someone in your family as mm/dd/yy. 05/15/1979a = -5, b = 15, and c = 79Use the following algebraic expressions for parts 3-5 of the discussion: ofor this expression I am replacing variable a with the month as a negative integer. I will plug in +15 for the variable b.(-5)(-5)(-5) – (15)(15)(15)-125 – (3375)To solve this equation I have to change the second integer to the opposite sign and add the real numbers.-125+ (-3375) = -3500o²+ab+b²)for this expression I am replacing variable a with (-5) variable b with (15) (-20) (25+ -75 + 225)(-20) (-50 + 225)(-20) (175)-3500ooDid you notice anything interesting about the results of and ? Was this coincidence or do you think there is a reason for this?
