BRB TOMMOROW

Step-by-step explanation:

Given factors are the true factor of equation.

Step-by-step explanation:

Given : Factors (x+4),(x-3) and (x-7) of x^3-6x^2-19x+84x

3

−6x

2

−19x+84

To find : Show that factors are true?

Solution :

We multiply the factor to find the equation if the equation is same as given equation then factors are true.

Equation is (x+4)(x-3)(x-7)(x+4)(x−3)(x−7)

=(x^2-3x+4x-12)(x-7)=(x

2

−3x+4x−12)(x−7)

=(x^2+x-12)(x-7)=(x

2

+x−12)(x−7)

=x^3+x^2-12x-7x^2-7x+84=x

3

+x

2

−12x−7x

2

−7x+84

=x^3-6x^2-19x+84=x

3

−6x

2

−19x+84

Equations are same.

Therefore, Given factors are the true factor of equation.
