If p(x) = 2x2 - 4x and q(x) = x - 3, what is (p•q)(x)
Solution:
It is given that
p(x) = 2x2 - 4x
q(x) = x - 3
We have to find (p•q)(x)
(p•q)(x) = p(x) . q(x)
Substituting the values
= (2x2 - 4x) (x - 3)
Using the distributive property
= 2x3 - 6x2 - 4x2 + 12x
= 2x3 - 10x2 + 12x
Therefore, (p•q)(x) = 2x3 - 10x2 + 12x.
If p(x) = 2x2 - 4x and q(x) = x - 3, what is (p•q)(x)
Summary:
If p(x) = 2x2 - 4x and q(x) = x - 3, (p•q)(x) = 2x3 - 10x2 + 12x.
