so ... what did you get, and what are the rules for entering your solution online?
i have two problems that require using the quadratic formula to find the x-intercept of the parabola:
1. f(x)=-32x^2-4x+1
2. y=7x^2-9x+1
I have to enter to xintercepts into an online homework program and it keeps on telling me im wrong!! please help!
okay, for the first one i got -3- sq root 40/-2 and 6+ sq root 40/-2
and the second one i got 10/32 and -1/8
the format will allow me to use the sq root symbol and fractions but apparently my answers are wrong! i dont know what i am doing wrong!! if anyone can help me understand that would be awesome thanks!
