<PRE><B>Question 945674</B>
75 - 60m + 12m^2
12m^2 - 60m + 75 = 0
12mm - 60m + 75 = 0
---
the above quadratic equation is in standard form, with a=12, b=-60 and c=75
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
12 -60 75
into this solver: http://sooeet.com/math/quadratic-equation-solver.php
---
the quadratic has two real roots at:
---
m = 2.5
m = 2.5
---
answer:
(m - 2.5)(m - 2.5)
---
now, solve by a different method: completing the square:
---
(12mm - 60m + 75 = 0)/12
mm - 5m + 6.25 = 0
mm - 5m + (5/2)(5/2) + 6.25 = (5/2)(5/2)
mm - 5m + (2.5)*(2.5) = (2.5)*(2.5) - 6.25
mm - 5m + (2.5)*(2.5) = 6.25 - 6.25
mm - 5m + (2.5)*(2.5) = 0
---
answer:
(m - 2.5)(m - 2.5)
