trying to solve this equation (4x + 1 )(x2 – 9x + 5)? any ideas? do I multiply 4x by the 2nd problem in () or 4x+1 by the problem? **Weegy:** Solution: An example of a problem very similar to this one is (3x + 1)(x^2 - 9x + 2)
Solution:
(3x + 1)
(x^2 - 9x + 2)
- - - - - - - -
3x^3+x^2-27x^2-9x+6x+2
3x^3-26x^2-3x+2 ans.

(4x + 1 )(x^2 – 9x + 5)

= 4x^3 - 36x^2 + 20x + x^2 – 9x + 5

= 4x^3 - 35x^2 + 11x + 5

= 4x^3 - 36x^2 + 20x + x^2 – 9x + 5

= 4x^3 - 35x^2 + 11x + 5
