Question

solve for x
x^2 -x+6=0

solve, give exact and approx to 3 decimals
x^2+7x-5

Answer 1

2nd equation =o, sorry!

Answer 2

that makes the equation be x^2-x-6 tho not +6

Answer 3

quadratic formula then
\[x=(-b \pm \sqrt{b ^{2}-4ac})\div2a\]
\[x=(1\pm \sqrt{1-4\times1\times6})\div2\times1\]
\[x=1\pm \sqrt{-25}\div2\]
you cannot sqare root a negative so there are no answers to the first part
