Hi I need help on these multiple choice questions

The solutions of the equation 3x^2+7x-5=0 are:

A.both rational B.both real C.not real D.equal and rational E. equal and real

The equation 9x^2-24x+16 has:

A.no real solutions B.one rational solution C.two rational solutions D.one irrational solution E.two irrational solutions

The equations 3x^2+6x+4 has:

A.no real solutions B.one rational solution C.two rational solutions D.one irrational solution E.two irrational solutions

The equation ax^2+bx+c=0, where b>a>c>0 has:

A. no real solutions B:two real solutions of opposite signs C.two real negative solutions D.two real positive solutions E.insufficient information to determine the type of solutions


I just don't get all the real, rational stuff
Thanks

Real means not imaginary or complex, an imaginary or complex number involves the square root of a negative number, so real means a number that does not involve the square root of a negative number.

Rational means that it is expressable in the form \frac{A}{B} where A and B are integers. For example, \pi and \sqrt{2} are irrational, because they cannot be expressed in this way.

Does this help? Please ask if you need further guidance :)

Yea it kind of does
But I wouldn't know the way to solve it
Thanks

Well you either factorise or use the quadratic formula. You should have been taught how to do both of these.

Yes I have
Thanks so much
