what is x square - 3 x +
Answer: The equation represents a parabola opening downwards with x-intercepts at and , and its vertex at .
Step-by-step solution
Step 1: Identify the equation type
The given equation is . This equation involves two variables, and , and the highest power of is 2, while the highest power of is 1. This structure indicates that it represents a parabola.
Step 2: Rearrange the equation to standard form
To better understand the parabola's properties, we can rearrange the equation to express in terms of . By moving the terms to the right side of the equation, we get . This is the standard form for a parabola opening downwards.
Step 3: Find the roots (x-intercepts)
To find where the parabola intersects the -axis, we set . This gives us . Factoring out , we get . This implies that or . So, the parabola crosses the -axis at and .
Step 4: Find the vertex
For a parabola in the form , the -coordinate of the vertex is given by . Here, and , so . Substituting this value back into the equation, we find the -coordinate: . Thus, the vertex is at .
