fixt 3x3 + 5x2 - 16x - 2
Answers
The factor of 3x3 + 5x2 - 16x - 2 is (3x + 2) • (x + 3) • (x - 2)
Explanation:
What is the factor of 3x3 + 5x2 - 16x - 12
Solution:
= [3 • (x^3) + 5x^2) - 16x] - 12
= x^2 ( 3x - 5x) - ( 16 x + 12)
= x^2 ( 3x - 5x ) - 2 ( 8x + 6 )
= (x^2 - 2) ( 3x - 5x ) (8x + 6 )
Or
= [3 • (x^3) + 5x^2) - 16x] - 12
= [(3x^3 + 5x^2) - 16 x] - 12
= [(3x^3 + 5x^2) - 16x] - 12 ( It is not a perfect cube)
= (3x + 2) • (x + 3) • (x - 2)
Given:
To find:
Factor=?
Solution:
In the given question there is some mistyping error so the correct equation can be described as follows:
factor the above equation:
by hit and trail method we put the value 2 in the x so, wet get the value that is equal to: 0
is one factor of the equation and we divide the value by so it will give another fraction value and to factor that value we get the value that is:
The final answer to this equation is:
