Determine what type of number the solutions are and how many exist for the equation 3x^2+7x+5=0

Mathematics

Hitman42 [59]3 years ago

Answer:

Two complex (imaginary) solutions.

Step-by-step explanation:

To determine the number/type of solutions for a quadratic, we can evaluate its discriminant.

The discriminant formula for a quadratic in standard form is:

\Delta=b^2-4ac

We have:

3x^2+7x+5

Hence, a=3; b=7; and c=5.

Substitute the values into our formula and evaluate. Therefore:

\Delta=(7)^2-4(3)(5) \\ =49-60\\=-11

Hence, the result is a negative value.

If:

  • The discriminant is negative, there are two, complex (imaginary) roots.
  • The discriminant is 0, there is exactly one real root.
  • The discriminant is positive, there are two, real roots.

Since our discriminant is negative, this means that for our equation, there exists two complex (imaginary) solutions.

In a right triangle, the measure of one acute angle is 26°. What is the measure of the other acute angle?
Makovka662 [10]
The sum of the angles of a triangle ALWAYS sum up to 180 degrees.  So to find the other angle, you would take 180, subtract 90, and then subtract 26, to get 64.
The measure of the 3rd angle equals 64.
