Answer:
![p(x) = x^{3} + 3x^{2} -4 = (x-1)(x+2)(x+2)](https://tex.z-dn.net/?f=p%28x%29%20%3D%20x%5E%7B3%7D%20%2B%203x%5E%7B2%7D%20%20%20-4%20%3D%20%28x-1%29%28x%2B2%29%28x%2B2%29)
Step-by-step explanation:
The given polynomial ![p(x) = x^{3} + 3x^{2} -4](https://tex.z-dn.net/?f=p%28x%29%20%3D%20x%5E%7B3%7D%20%2B%203x%5E%7B2%7D%20%20%20-4)
Now, given that (x-1) is a factor of the above equation.
Now, divide the given polynomial with the factor (x-1)
By Long division, we get
Quotient =
and Remainder = 0
So, by the <u>Remainder theorem</u>
Now, Simplifying the quotient further, we get
=
=
or,
= (x+2)(x+2)
Hence, the given polynomial
can be written as a product of linear factors.
![p(x) = x^{3} + 3x^{2} -4 = (x-1)(x+2)(x+2)](https://tex.z-dn.net/?f=p%28x%29%20%3D%20x%5E%7B3%7D%20%2B%203x%5E%7B2%7D%20%20%20-4%20%20%3D%20%28x-1%29%28x%2B2%29%28x%2B2%29)
Step-by-step explanation:
Given
w(x) = - 3x - 4
Now
w(7) = - 3 * 7 - 4
= - 21 - 4
= - 25
Hope it will help :)❤
