X²-10+3x=0 la ecuación es completa o incompleta?

hjlf

Answer:

Yes, the equation is complete.

Step-by-step explanation:

The given quadratic equation, x² + 3x - 10 = 0 is expressed in standard form, ax² + bx + c = 0.

Where: a = 1, b = 3, and c = -10.

Using the quadratic formula:

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

We can solve for its solution by plugging in the values for a, b, and c.

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

$x = \frac{-3 (+/-) \sqrt{(3)^{2} - 4(1)(-10)} }{2(1)}$

$x = \frac{-3 (+/-) \sqrt{9 + 40} }{2}$

$x = \frac{-3 (+/-) \sqrt{49} }{2}$

$x = \frac{-3 + 7 }{2}$ , $x = \frac{-3 - 7 }{2}$

$x = \frac{4}{2} = 2$ , $x = \frac{-10 }{2} = - 5$

Therefore, the solutions of the quadratic equation, x² + 3x - 10 = 0 is:

x = 2, and x = -5

What is the domain and range of (-2,5) (0,3) (2,2) (-4,0) (2,-3)

Nina [5.8K]

Answer:

Domain- -4,-2,0,2 Range- -3,0,2,3,5

Step-by-step explanation:

(x,y)

The domain is the x

The range is the y

And if the number is there more than once you only have to list it once.

Typically you list them from least to greatest so the smallest number the higher number.
