Answer 2

Hello

Factorize 2x^2 - 3x^2 - 17x + 30 ?

$-x^{2} - 17x + 30$

$\Delta = (-17)^{2} - 4 \times -1 \times 30$

$\Delta = 289 + 120 = 409$

$\sqrt\Delta = \sqrt409$ > 0 so 2 Solution

$x_{1} = \frac{17 - \sqrt409}{2 \times -1}$

$x_{1} = \frac{-17 + \sqrt409}{2}$

$x_{2} = \frac{17 + \sqrt409}{2 \times -1}$

$x_{2} = \frac{-17 - \sqrt409}{2}$
