Question

Determine whether (x_2)is a factor of polynomial x2+2x-3 or not​

Answer 1

hey mate

x-2=0

x=2

p(2)=2×2+2×2-3

4+4-3

=5

therefore (x-2) is not a factor of The polynomial

$\huge\mathfrak\red{Question:}$

Determine whether (x-2) is a factor of polynomial x^2 + 2x - 3 or not​.

$\huge\mathfrak\blue{Solution:}$

x - 2 = 0
x = 2

p(x) = x^2 + 2x - 3

p(2) = (2)^2 + (2×2) - 3

p(2) = 4 + 4 - 3

p(2) = 8 - 3

p(2) = 5

Therefore, (x-2) isn't a factor of polynomial x^2 - 2x + 3.
