Question

find the value of m, if (- 4) is a zero of the polynomial x2 + 3x + m​

Answer 1

Answer:

(-4)2 +3*-4+m=0

16-12+m. =0

4+m =0

m=-4

Answer 2

Step-by-step explanation:

x^2 + 3x + m = 0

put x = -4 in the above equation then we get the value of m

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

16 -12 + m = 0

4 + m = 0

m = -4
