If the discriminant is 16 in a quadratic equation what is true about its solutions

If the discriminant is a positive number, there will be 2 possible solutions. If you replace the entire section of b²-4ac with 16, you will see that the equation becomes; (-b+-√16)/2a --> leading to an answer with the + and another with the -. 

If the discriminant is 0, there will be 1 possible solution, (again replace this into the discriminant value) (-b)/2a ---> this formula is used to also find the x coordinates of a vertex, fyi. 

If the discriminant is a negative number, there will be no solution (since squareroot of a negative number is not possible) 

Hope I helped :)

Answer:

x = 36.3°

using tane rule:

\sf tan(x)= \dfrac{opposite}{adjacent}

Here!

  • x = missing angle
  • opposite = 22
  • adjacent = 30

=============

\hookrightarrow \sf tan(x) = \dfrac{22}{30}

\hookrightarrow \sf x= tan^{-1}(\dfrac{22}{30} )

\hookrightarrow \sf x= 36.253^{\circ \:}

\hookrightarrow \sf x= 36.3^{\circ \:}        ( rounded to nearest tenth of a degree)
