Question

4. Find the zeroes of quadratic polonomial 3x2_x-4 math question 10th class​

Answer 1

$\sf\small\red{Given:-}$

$\sf\rightarrow {3x}^{2} - x - 4$

$\sf\small\red{find:-}$

$\sf\rightarrow \: zero \: of \: polynomial$

$\sf\small\red{Solution:-}$

$\sf\hookrightarrow \: {3x}^{2} - 4x + 3x - 4 = 0$

$\sf\hookrightarrow \: x(3x - 4) + 1(3x - 4) = 0$

$\sf\hookrightarrow(3x - 4)(x + 1) = 0$

Note:-

$\sf\dashrightarrow \: zero \: of \: polynomial \: are \: x = \frac{4}{3} and \: x = - 1.$
