How do you factorise x^2+7x?

➷  You find the largest value or 'letter' that is shared by both

In this case, you can see the largest common value shared by x^2 and 7x is simply just 'x'

Place 'x' outside the parenthesis and inside the parenthesis place the values you would multiply by x to reach the original expression

Your answer is:

x(x + 7)

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

the answer is 1030 it's very simple math.
