Step-by-step explanation:
<u>Roots of a quadratic equation</u>
The standard representation of a quadratic equation is:
where a,b, and c are constants.
Solving with the quadratic formula:
The argument of the radical is called <em>the discriminant</em>:
The nature of the solutions of the equation depends on the value of d as follows:
- If d is zero, there is only one real (and rational) root.
- If d is positive, there are two real unequal roots. If also d is a perfect square, then the roots are also rational. If d is not a perfect square, the roots are irrational.
- If d is negative, there are two unequal complex roots.
We are given the equation:
Here: a=-2, b=6, c=5. The discriminant is:
d = 116
Since d is positive and a non-perfect square, the roots are:
b. real, irrational, and unequal
Answer:
- Quadrant II
- Quadrant IV
- <em>y</em> axis
Step-by-step explanation:
Quadrant I is written in the format: (x,y)
Quadrant II is written in the format: (-x,y)
Quadrant III is written in the format: (-x,-y)
Quadrant IV is written in the format: (x,-y)
Points on the <em>x</em> axis are written in the format: (x,0) or (-x,0)
Points on the <em>y</em> axis are written in the format: (0,y) or (0,-y)
Hope it helps!
