What is the factored form of x2 – x – 2? (x – 2)(x 1) (x 2)(x 1) (x – 2)(x – 1) (x 2)(x – 1)
1 answer:
A quadratic equation is an equation whose leading coefficient is of the second degree. The factored form of the quadratic equation x²-x-2 is (x+1)(x-2).
<h3>What is a quadratic equation?</h3>A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.
It is written in the form of ax²+bx+c.
The factored form of the quadratic equation can be done in the following manner,
Thus, the factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

Answer:
Option A is correct
The only figure after composition of to figure R is Figure H
Step-by-step explanation:
From the given figure in R;
The coordinates in Figure R ;
(1 , -1) , (2, -2) ,(4, -2) ( 0, -4)
Composite function defined as when one function is substituted into another function.
To Apply the composition to figure R;
First apply the Reflection in Figure R;
The rule of reflection is given by:
By applying the rule of reflection in Figure R ,
then, the coordinates becomes;
(1 , -1) (1, 1)
(2 , -2) (2, 2)
(4 , -2) (2, 4)
(0, -4) (4, 0)
Now, apply the translation
Translation : It is a type of transformation that moves each point in a figure the same distance in the same direction.
then,
the rule of translation is:
Apply the rule of translation on coordinates (1,1) , (2,2), (2,4) and (4,0)
then
(1 , 1) (1+0 1+3) =(1,4)
(2, 2) (2+0 2+3) =(2, 5)
(2, 4) (2+0 4+3) =(2 ,7) and
(4, 0) (4+0 0+3) =(4 ,3)
Then, the only figure after composition of to figure R is Figure H
