Answer:
<em>x² + 2x - 15 = 0 </em>
Step-by-step explanation:
- 5 and 3 are zeros of quadratic function.
(x + 5)(x - 3) = 0
<em>x² + 2x - 15 = 0</em>
B=7
3(b-4)+5b=44
3b-12+5b=44
8b=44+12
8b=56
b=7
Answer:
3x^2 is the final solution
See the image below for step by step explanation.
The graph of a quadratic function is a parabola. The axis of symmetry<span> of a parabola is a vertical line that divides the parabola into two congruent halves. The </span>axis of symmetry<span>always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the </span>axis of symmetry<span> of the parabola.</span>
