Answer:
Step-by-step explanation:
The given quadratic equation is expressed as
x² - 6x - 40 = 0
The equation is already in the standard form of ax² + bx + c
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 1
b = - 6
c = - 40
Therefore,
x = [- - 6 ± √(- 6² - 4 × 1 × - 40)]/2 × 1
x = [- 6 ± √(36 - - 160)]/2
x = [- 6 ± √196]/2
x = (- 6 + 14)/2 or x = (- 6 - 14)/2
x = 8/2 or x = - 20/2
x = 4 or x = - 10

<span>Instead of k, k+1, k+2, you should use k, k+2, k+4 with the constraint that k is even (i.e. if you return an odd integer for k, or a non-integer, then return no solution).
</span><span>k + (k+2) + (k+4) = 4k
</span><span>3k + 6 = 4k
k = 6
</span><span>Indeed, 6+8+10 = 4*6.</span>

Answer:
Given function:
To graph the line using inputs -1,0,1 and 2.
Solution:
In order to find the points to be plot on graph we will plugin the input values as in the given function.
1) When
Point (-1,4)
2) When
Point (0,3)
3) When
Point (1,2)
4) When
Point (2,1)
The points to be plot in the graph are:
(-1,4),(0,3),(1,2),(2,1)
