Question

the factor of given polynomial is (x+5)
then find the other
x² + x–20​

Answer 1

Answer:

10 Answer...

Step-by-step explanation:

If (x+5) is a factor of x square + x - 20

then, p(-5) = 25 + 5 - 20

= 30 - 20

= 10 Answer

Answer 2

1. multiply x+5 with x we get x^2+5x

2.do subtraction and we get -4x

3.bring down -20 then equation will be -4x-20

4.multiply x+5 with -4 we get -4x-20

5.do subtraction

6. we get x-4 as other polynomial
