Answer:
Well, I am not sure which one is equivalent to another, but I have some information that should help you find your answer.
Step-by-step explanation:
The simplified expression to x2 − x − 6 x2 + 2x − 15 would be equal to −5 x 2 + x − 15.
The simplified expression to x + 3 x + 5 would be equal to 4x + 5.
The simplified expression to x + 2x + 5 would be equal to 3x + 5.
The simplified expression x + 3 x − 3 would be equal to 4x − 3.
The last simplified expression to x + 2 x − 3 would be equal to 3x − 3.
Hope this helps, I am really sorry if I didn't answer your question properly, or the way you asked!
f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. FYI: Different textbooks have different interpretations of the reference "standard form" of a quadratic function.
The standard form of a parabola is y=ax2++bx+c , where a≠0 . The vertex is the minimum or maximum point of a parabola. If a>0 , the vertex is the minimum point and the parabola opens upward. If a<0 , the vertex is the maximum point and the parabola opens downward.
