Question

Find the value of m, If (x-2) is a factor of the polynomial 2x² -6x2*mx + 4
​

Answer 1

Answer:

Answer

Correct option is

A

-3

Consider the given polynomials x−1,3x

2

+mx

Given that x−1 is factor of 3x

2

+mx

So,

x−1=0

x=1

x=1 will satisfied 3x

2

+mx

Now,

3x

2

+mx=1

3.1

2

+m×1=0

3+m=0

m=−3

Hence this is the answer .7

Step-by-step explanation:

example For what value of p, is (−4) a zero of the polynomial p(x)=x

2

−2x−(7p+3) ?

Answer

p(x)=x

2

−2x−(7p+3)

If −4 is a zero of the polynomial,

p(−4)=0

(−4)

2

−2(−4)−(7p+3)=0

16+8−(7p+3)=0

16+8=7p+3

7p=21

p=3
