Answer 1

Answer:

$x = -1$

explanation:

$x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{2a} \\\\when \\\\ax^2 + bx + c = 0$

given equation: 2x² + 5x + 3

using quadratic formula:

$x = \frac{ -b + \sqrt{b^2 - 4ac}}{2a}$

$x = \frac{ -5 + \sqrt{5^2 - 4(2)(3)}}{2(2)}$

$x = \frac{ -5 +\sqrt{25 - 24}}{4}$

$x = \frac{ -5 +\sqrt{1}}{4}$

$x = \frac{-5 +1}{4}$

$x = \frac{-4}{4}$

$x = -1$

Answer 2

Answer:

-1

Step-by-step explanation:

=> -5 + √25 - 4(2)(3) / 4

=> -5 + 1 / 4

=> -4 / 4

=> -1
