text: values of b? can someone help me with these two problems all values of b in the following equations that will give one or more real number solutions. 1# 5x^2+bx+1=0 2# -3x^2+bx-3=0 for realsolutions thecondition is b^2>4ac 1.b^2-4ac must be positive b^2>20   2.b^2>4ac or b^2-4ac positive =>b^2-4ac must be greater than zero  =>b^2>36
