Question

if x+4 is a factor of the polynomial x^2 + 3x +m find the value of m​

Answer 1

Answer:

X+4 is a factor

therefore,X=-4

Step-by-step explanation:

(4)^2+3(4)+m=0

16+12+m=0

28+m=0

m=-28

Answer 2

x+4 is factor of x² +3x+m

x+4=0

x=−4 is zero of polynomial

Put it in polynomial

(−4)²+3(−4)+m=0

16−12+m=0

m=−4
