Question

can anyone tell me how to solve this questions

1. Determine if ( X + 1) is a factor of x3 + x2 + X + 1
x2=xsquare
x3=xcube

2.find that (2,3) is a solution of the equation 2x+3y=5

Answer 1

Answer:

Step-by-step explanation:

Divide the polynomial by given factor.

(X³ + x² + x + 1) ÷ (x+1) = x² + 1

Therefore, x+1 is a factor of the given polynomial.

2. Put x = 2 and y = 3

Therefore, 4+9 ≠ 5.

Therefore,(2,3) is not a solution of given equation.
