Answer 2

$\sf\huge\blue{\underline{\underline{ Question : }}}$

The sum of zero of 3x² + 5x - 2 is...?

$\sf\huge\blue{\underline{\underline{ Solution : }}}$

★ Given that,

• P(x) = 3x² + 5x - 2 = 0

★ To find,

• Sum of the zeroes : (α + ß)

★ Let,

According to the general form of quadratic polynomial : ax² + bx + c.

• a = 3
• b = 5
• c = - 2

$\bf\green{:\implies Sum\:of\:the\:zeroes\:= \alpha + \beta = \frac{-b}{a}}$

$\bf\:\implies \frac{-5}{3}$

And also...

$\bf\green{:\implies Product\:of\:the\:zeroes\:= \alpha \beta = \frac{c}{a}}$

$\bf\:\implies \frac{-2}{3}$

Hence,it was solved...
