Question

3a^3 +4a -3 উৎপাদকে বিশ্লেষণ​

Answer 1

Given:

In the given equation there is mistyping error so, the correct equation can be defined as follows:

$\bold{3a^2+4a-3}$

To find:

find product=?

Solution:

$\to 3a^2+4a-3$

compare the value with: $ax^2+bx+c=0$

$a= 3\\b=4\\c=-3$

if  $\alpha \ \ and \ \ \beta \ were \ roots$

$\alpha +\beta =\frac{-b}{a}\\\\\alpha \beta = \frac{c}{a}$

The product of roots were:

$\to \frac{-3}{3}\\\\\to -1$
