okay...
I had a problem:
The width of a rectangular park is 5m shorter than its length. If the area of the park is 300m². Find the length and the width.
I made this equation:
x(x+5)=300
And here are my Steps:
x(x+5)=300
x²+5x=300
X²+5x-300=0
x=-5±√5²-4(1)(300)/2
x=-5±√25-1200/2
x=-5±√-1175/2
okay what do I do from there? I thought a square root of something negative was impossible? Oh and the slashes mean it is a fraction. HELP PLEASE!!!!
These are all "solving problems involving quadratic equations" and I need major help with them!!!
Thanks
