Question

3x2 + 5x + 7 = 0

Round the solution to the nearest 100th.

Answer 1

I think it is no real solutions

Answer 2

if you can't factorize, which in this case you can't since the solution has to be rounded, then use the quadratic formula.

\[[-b \pm \sqrt{b^2-4ac}]/2a\]

Answer 3

where a is the coefficient in front of x^2
b is the coefficient in front of x
and c is the constant at the end.

Answer 4

@Migitmack
u r right there is no real solution since b^2-4ac=-59
