Question

If zeroes of the polynomial x^2+4x+2a are alpha and 2 by alpha, then find the value of a

Answer 1

Step-by-step explanation:

If the zero of the polynomial x^2 + 4x + 2a are alpha and 2alpha , then find the value of a .

Answer 2

Answer:

a=1

Step-by-step explanation:

product of the roots is 2a

then

$\alpha \times (2 \div \alpha ) = 2$

$2a = 2$

$a = 1$
