Subtract 7x^2−5xy+8y2 from −2x^2−15xy+9y^2

Answer

Subtract from

then;

Remove the bracket we have;

Like terms are those terms which have same variable to the same power.

Combine like terms;

Therefore, Subtracting from we get

(- 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 )
