Okay for my Algebra 2 class we are currently on the chapter of Quadratic Equations. On this worksheet I have it says to find the square root of:
108x^2 = 147
I am not really sure how to work this problem out. Please help? And another problem I do not understand is :
4x^2 - 2x - 30 = 0
for this problem above I saw that it could be turned into :
2(x^2-x-15)=0
but after that I am stuck because I have to find two numbers that are factors of negative 15 but also add up to negative 1? And I can't think of any or I am not sure if what I did was incorrect?
Please help.
