Question

The sum of zeroes of P(x) = 3x2 +5X-2
is​

Answer 1

Answer:

let's keep x=1

6+5-2

6+3

9 is the answer

Answer 2

Answer :-

The sum of zeros of P(x) = 3x² + 5x - 2 is (-5/3)

Solution :-

$\longrightarrow p(x) = 3 {x}^{2} + 5x - 2$

Comparing this Polynomial with (ax² + bx + c) →

• a = 3

• b = 5

• c = -2

We know that :-

$if \: \alpha \: and \: \beta \: are \: the \: zeros \: of \: this \: polynomial \: \\ Then, \alpha + \beta = - \frac{b}{a}$

So,

$\longrightarrow \bold{ \alpha + \beta = - \frac{5}{3}}$

Hence , the sum of zeros of this Polynomial is (-5/3) .
