Question

chek wether x+3is factor of the polynomial by using factor theorem .
$p(x) = {x}^{2} + 2x - 3$
​

Answer 1

Answer:

yesss

Step-by-step explanation:

Factorising x2 + 2x - 3

x2 + 3x - x - 3

x(x+3) -1(x+3)

(x+3)(x-1)

therefore (x+3) is a factor of the polynomial

Answer 2

Answer:

» p (x) = x² + 2x - 3

» p (x) = x² + 3x - x - 3

» p (x) = x (x + 3) - (x + 3)

» p (x) = (x + 3) (x - 1)

Therefore, x + 3 is the factor.
