<span>the value under the square root i.e. b²-4ac is called Discriminant (D) and its value tells us about the nature of the roots of the equation. If D = 0, the roots are real & equal if D > 0, the roots are real & different if D< 0, the roots are imaginary & different</span>
12 and the exponent would be 144
Hope this helped :)
Hope this answer your question :)
Answer:
Triangle angles put together always have to add up to 180 degrees as long as you have two of them you can always find the third.
Step-by-step explanation:
