How many, and what type of, solutions does 6x^2 - 2X + 7 = 0 have?


1 rational solution

2 no real solutions

2 rational solutions

2 irrational solutions

Verified Answer :

yo need to use discriminant

for ax²+bx+c=0
the discriminat is b²-4ac

if the discriminant is
1. less than 0, then 0 real solutions
2. equal to 0, then 1 real solutions
3. if more than 0, then 2 real solutions

given

6x²-2x+7=0
a=6
b=-2
c=7
(-2)²-4(6)(7)
4-168
we can see this is less than 0
no real solutions

According to the discriminant of the quadratic equation, it is found that 6x^2 - 2X + 7 = 0 has 2 no real solutions.

What is the discriminant of a quadratic equation and how does it influence the solutions?

A quadratic equation is modeled by:

\(y = ax^2 + bx + c\)

The discriminant is:

\(\Delta = b^2 - 4ac\)

The solutions are as follows:

  • If \(\mathbf{\Delta > 0}\), and it is a perfect square, it has 2 rational solutions.
  • If \(\mathbf{\Delta > 0}\), and it is not a perfect square, it has 2 irrational solutions.
  • If \(\mathbf{\Delta = 0}\), it has 1 rational solutions.
  • If \(\mathbf{\Delta < 0}\), it has 2 complex solutions.

In this problem, the equation is:

\(6x^2 - 2x + 7 = 0\)

Hence the coefficients are a = 6, b = -2, c = 7 and the discriminant is given by:

\(\Delta = (-2)^2 - 4(6)(7) = -164\)

Negative discriminant, hence the correct option is 2 no real solutions.
