jok3333 [9.3K]

Answer:

It would be True

Step-by-step explanation:

2+5x = -8

SUBTACT 2 on both sides and it would look like this:

5x = -8 - (2)

5X= -10

then DIVIDE 5 both side to get "X" ALONE,

x= -10/5

then divide -10 with 5

equal to:

x = -2

HELP PLZ DUE RN BRAINIEST TO WHOEVER RIGHT
Y_Kistochka [10]

Answer:

x = \dfrac{2}{5} + \dfrac{\sqrt{14}}{5}   or   x = \dfrac{2}{5} - \dfrac{\sqrt{14}}{5}

Step-by-step explanation:

5x^2 - 2 = 4x

5x^2 - 4x - 2 = 0

x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}

x = \dfrac{-(-4) \pm \sqrt{(-4)^2 - 4(5)(-2)}}{2(5)}

x = \dfrac{4 \pm \sqrt{16 + 40}}{10}

x = \dfrac{4 \pm 2\sqrt{14}}{10}

x = \dfrac{2 \pm \sqrt{14}}{5}

x = \dfrac{2}{5} + \dfrac{\sqrt{14}}{5}   or   x = \dfrac{2}{5} - \dfrac{\sqrt{14}}{5}
