<u>Answer</u>:

x = -1

<u>explanation</u>:

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

given equation: 2x² + 5x + 3

<u>using quadratic formula</u>:


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

−7/2÷7/5 i do not get it PLZ HELP!!! ASAP
yulyashka [42]
Okay, to start, when dividing fractions, one thing I use is to flip the numerator and denominator of the divisor and change the division sign to a multiplication sign so it would look like this: 
-7/2*5/7
Then, you would multiply straight across and you would get -35/14 which simplifies to -5/2.
