Question

If alpha and beta are the zeroes of the quadratic polynomial 2x


- x + 3, then find the value of

alpha+beta= ? (ii) alpha*beta= ?​

Answer 1

Answer:

1) alpha + beta = 1/2

2) alpha × beta = 3/2

Step-by-step explanation:

1)we know that alpha + beta = -(b)/a

so here value of 'b' & 'a' coefficients are -1 & 2 respectively....

so alpha + beta = -(b)/a = -(-1)/2 = 1/2

2)we know that alpha × beta = c/a

here the values of 'c' & 'a' coefficients are 3 & 2 respectively.....

so alpha × beta = c/a = 3/2
