Question

if x-1is afactor of the polynomial 3x_square +mx then find the value of m​

Answer 1

Value of m is -3

Step-by-step explanation:

GIVEN THAT

• (x - 1) is a factor of the polynomial ( 3x² + mx )

So we have

• x - 1 = 0
• x = 1

Now

• p(x) = 3x² + mx

• p(1) = 0

• 3(1)² + m*1 = 0
• 3 + m = 0
• m = -3
