Question

check whether (x+2) is a factor of x^3 +5x^2-7x+3
Plzzz answer ​

Answer 1

Step-by-step explanation:

this the method I suggest

hope this helps

pls mark as the brainliest

Answer 2

p(x)=x³+5x²-7x+3

p(-2)= x³+5x²-7x+3 = 0

-2³+5*-2²-7*-2+3= 0

-8+20+14+3= 0

= 29≠ 0

As RHS≠LHS (x+2) is not a factor of p(x)= x³+5x²-7x+3
