Question

If one of the factor of
p(x)=x² +x -20 is (x+5). Find the other:

options :

• x-4

• x+2

• x+4

• x-5​

Answer 1

Answer:

x+2

I hope this answer is useful

Answer 2

Answer:

x-4

Explanation:

p(x)=x² +x -20

Factorisation

x²-4x+5x-20 =0

=> x(x-4)+5(x-4) =0

=> (x-4)(x+5) =0

=> x-4 = 0 ,x+5 = 0

=> x = 4, x = -5.

hence (x-4)(x+5) these are the factors
