Question

one of the root of equation x2-3x+a is 2 then a is??​

Answer 1

Answer:

a = 2

Step-by-step explanation:

We have,

p(x) = x² - 3x + a

Now, we are also given,

x = 2

So,

p(2) is a factor of p(x),

Thus,

p(2) = 0

Then,

p(x) = x² - 3x + a

p(2) = (2)² - 3(2) + a

0 = 4 - 6 + a

0 = a - 2

a = 2

Hence,

a = 2
