if 2 is a zero of polynomial x2-3x+a then find the value of a?​

Answer 1

Answer:

$\huge\mathcal{AnsweR..}$

2 is a zero of x2+3x+a

Thus, (2) is a zero of polynomial...

2 +3(2)+a=0

a+10=0

a=−10

Answer 2

Answer:

p(x)= x²-3x +a

p(2)= 2² - 3(2)+ a =0

= 4 - 6 + a =0

= 4-6 = -a

= - 2 = -a

a = 2
