Question

29. If the sum and difference of zeroes of quadratic polynomial are – 3 and - 10, respectively. Then, the difference of the squares of zeroes is​

Answer 1

Answer:

3,10 is the answer of these

Answer 2

Answer:

the difference of the squares of zeroes is​ $30$

Step-by-step explanation:

Given:

$\alpha +\beta =-3\\\\\alpha -\beta =-10$

we need to find the $\alpha ^2-\beta ^2$

As we can write

$\alpha ^2-\beta ^2=(\alpha +\beta )(\alpha -\beta )$

We get as

$=(-3)(-10)\\\\=30$
