Question

the product of the zeros of the quadratic polynomial x²-3ax+2a²-1 is 7 is negative of the other, then a=​

Answer 1

Answer:

a=2

Step-by-step explanation:

Product of zeroes=7 (Given)

Now,

We know that,

$\alpha \times \beta = \frac{c}{a}$

7=2a²-1

7+1=2a²

8=2a²

4=a²

2=a

Therefore, value of a is 2.
