Question

if 2 is a zero of the polynomial ,ײ -3×+ a then find the value of "a"?​

Answer 1

Answer:

2

Step-by-step explanation:

We know that 2 is a zero,

Therefore,put x=2

So, (2)² - 3(2) +a = 0

4-6+a = 0

-2+a = 0

a=2

Answer 2

Answer:

$\huge{\boxed{\rm{\red{a=2}}}}$

Step-by-step explanation:

Given:-

2 is a zero of the polynomial ,ײ -3×+ a.

To find:-

Find the value of "a"?

Solution:-

Given polynomial p(x)=x²-3x+a

Given that,

2 is the zero of p(x)

Using Concept:-

Factor theorem:-

Let p(x) be a polynomial of the degree greater than or equal to 1 and (x-a )is another linear polynomial,if (x-a )is factor then p(a)=0

Procedure:-

If 2 is a zero of p ( x) then p(2)=0

=>p(2)=(2)²-3(2)+a=0

=>4-6+a=0

=>-2+a=0

=>a=2

Answer:-

The value of a=2
