Part 1: Create your own quadratic equation that cannot be solved by factoring, but can be solved using the quadratic formula. Id

eimsori [14]

when you use all prime, non-one numbers for b and c, it cannot be factored most of the time

example
1x^2+7x+5
a=1
b=7
c=5
x= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$
x= $\frac{-7+/- \sqrt{7^2-4(1)(5)} }{2(1)}$
x= $\frac{-7+/- \sqrt{49-20} }{2}$
x= $\frac{-7+/- \sqrt{29} }{2}$
x= $\frac{-7+ \sqrt{29} }{2}$ or $\frac{-7- \sqrt{29} }{2}$
