Answer:
1).
2).
Step-by-step explanation:
Here the given equation is
We have to factor the perfect square trinomial on the left side of the equation
So left side of the equation is
=
since [(a+b)²= a²+b²+2ab]
Therefore the factorial form of the equation will be
Now we have to solve the equation by applying square root property
The points of the graph of function be (0,-8) , (1,-15) ,(2,-24).
Given f(x)=(-x-4)(x+2)
We have to first multiply both the expressions to get f(x)
Expression refers to combination of numbers, symbols, variables, etc. It is usually not in equal to form. It expresses the relationship between variables. To find out the graph we need to first points of function.
f(x)=
Now we have to add 2x and 4x
f(x)=
Put the value of x=0
f(0)=0-0-8
=-8
Put the value of x=1
f(1)=-1-6-8
=-15
Put the value of x=2
f(2)=-4-12-8
=-24
Now plot these points on the graph to get the graph of function f(x)=(-x-4)(x+2).
