Question

1,5х-4х(в квадрате)=6,3х-х(в квадрате)

Answer 1

$1,5x-4x^2=6,3x-x^2$

$-4x^2+x^2=6,3x-1,5x$

$-3x^2=3,8x$

$-3x^2-3,8x$

дальше решаем квадратное

$-3x^2-3,8x=0$ 

получаем -19/15 и 0  

 

 

 

 

 

 

 

Answer 2

1,5x-4x^2=6,3x-x^2

-4.8x-4x^2+x^2=0

-4.8x-3x^2=0

D=(-4.8)^2-4*(-3)*0=23.04

x1=(4.8-(-4.8))/(2*(-3))=-9.6/6=-1.6
x2=(-4.8-(-4.8))/(2*(-3))=0

Answer 3

Let's solve this quadratic equation together!

The equation is $1.5x - 4x^2 = 6.3x - x^2$.

First, let's gather all the terms on one side of the equation to set it to zero:

$1.5x - 4x^2 - 6.3x + x^2 = 0.$

Combine like terms:

$-4x^2 + x^2 - 6.3x + 1.5x = 0.$

Now, simplify further:

$-3x^2 - 4.8x = 0.$

Factor out common terms:

$-x(3x + 4.8) = 0.$

Now, set each factor equal to zero and solve for $x$:

1. $x = 0$
2. $3x + 4.8 = 0$

For the second equation:

$3x = -4.8$

$x = -1.6.$

So, the solutions to the quadratic equation are $x = 0$ and $x = -1.6$.
