In a graph the roots of the function are given by the cut points with the x axis.
 On the other hand, we have the following equation:
 y = -x2 - x + 6
 To find the roots, we equate to zero:
 -x2 - x + 6 = 0
 Rewriting we have:
 x2 + x - 6 = 0
 (x-2) (x + 3) = 0
 The roots are:
 x1 = 2
 x2 = -3
 Answer:
 
The roots are:
 
x1 = 2
 
x2 = -3

Answer:

Roots are -3, 2

Step-by-step explanation:

y = −x^2 − x + 6

To find out the roots we set y=0 and solve for x

0 = -x^2 -x+6

Factor out -1

0=-1(x^2+x-6)

divide both sides by -1

x^2 +x -6=0, factor x^2 +x-6

product is -6 and sum +1

3* (-2) = -6

3-2= 1

so factors are 3 and -2

x^2 +x -6=0

(x+3)(x-2)=0

Set each factor =0 and solve for x

x+3 =0 , so x=-3

x-2=0, so x= 2

Roots are -3, 2

Paha777 [63]

Answer:

24 cm^2

Step-by-step explanation:

Find Side Length:  

20cm/4 = 5cm

Use x:  

First Diagonal - 4x; Second Diagonal = 3x  

Pythagorean Theorem:  

a^2 + b^2 = c^2  

Use Pythagorean Theorem:

a = 1/2 of First Diagonal  

b = 1/2 of Second Diagonal  

c = Side Length  

2x^2 + 1.5x^2 = 5^2

4x^2 + 2.25x^2 = 25  

6.25x^2 = 25

x^2 = 4

x = 2  

Formula for Area of Rhombus:

1/2 * First Diagonal * Second Diagonal

Use Formula for Area of Rhombus:

1/2 * 4(2) * 3(2)

= 1/2 * 8 * 6  

= 4 * 6

= 24 cm^2
