Question

Which of the following is a factor of 2x^3+13x^2+19x+20

Answer 1

Answer:

$(x+5)$

Step-by-step explanation:

$2x^3+13x^2+19x+20$

$\frac{2x^3+13x^2+19x+20}{x+5}$

$2x^2+\frac{3x^2+19x+20}{x+5}$

$2x^2+3x+\frac{4x+20}{x+5}$

$2x^2+3x+\frac{4x+20}{x+5}$

$2x^2+3x+4$

Now we got.

$\left(x+5\right)\left(2x^2+3x+4\right)$

$\left(x+5\right)$
