Factorise x 2 + 20 x + 100

(x+10)(x+10)

or (x+10)²

Step-by-step explanation:

this factories can use this

a² + 2ab + b²

; (a)² + 2(a)(10) + (b)²

= (a+b)²

hope it helps you ☺️

Any questions (ask me in comments)

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
