Factorise x square - 3 x minus 2​

Mathematics
1 answer:
lawyer [7]3 years ago
5 0

Answer:

The answer is below

Step-by-step explanation:

The equation x² - 3x - 2 cannot be factorized, I think the correct question is:

factorize x² - 3x + 2​

Solution:

A quadratic equation is a polynomial equation of the second degree (that is there is at least one term with a degree of 2).

The standard form of a quadratic equation is given by the equation:

ax² + bx + c = 0

Where a, b, and c being constants and x is the unknown variable.

Given:

x² - 3x + 2

= x² - 2x - x + 2

= x(x - 2) -1(x - 2)

= (x - 1)(x - 2)

What is meant by green mathematics?
ad-work [718]

The green mathematics tells about the impulse response of an in homogeneous linear differential operator.

According to the statement

we have to explain the green mathematics.

In mathematics, Actually there is a Green Function which was founded by a mathematician George Green.

In this function, a Green's function is the impulse response of an in homogeneous linear differential operator defined on a domain with specified initial conditions or boundary conditions.

The example of green function is the Green's function G is the solution of the equation LG = δ, where δ is Dirac's delta function; the solution of the initial-value problem Ly = f is the convolution (G ⁎ f), where G is the Green's function.

Actually in this function, it gives the relationship between the line integral of two dimensional vector over a closed path by a integral.

In this there is a green theorem, which  relates a line integral around a simply closed plane curve C and a double integral over the region enclosed by C.

So, The green mathematics tells about the impulse response of an in homogeneous linear differential operator.

Using 3.14 for 7, a sphere has a volume of 904.32 mm.
Alla [95]

Answer:

v =  \frac{4}{3} \pi {r}^{3 }  \\ 904.32 =  \frac{4}{3}  \times 3.14 \times   {r}^{3}   \\  {r}^{3}  =  \frac{3 \times 904.32}{4 \times 3.14}  = 21.57 \\ r = 2.78

then Radias equal to 5.5676

Step-by-step explanation:

I can help you solve what you want in mathematics in exchange for some money. If you want to, you can inform me about it and I will help you.

PLEASE HURRY 50 POINTS Answer Both parts and I will reward Brainliest
vlabodo [156]

We have:

a_1=-3

and:

r=4

so:

$\sum\limits_{n=2}^5\,-3\cdot4^{n-1}=\sum\limits_{n=1}^5\,-3\cdot4^{n-1}-a_1=S_5-a_1=\frac{-3-(-3)\cdot 4^5}{1-4}-(-3)=

=\dfrac{-3-(-3)\cdot 1024}{-3}+3=\dfrac{-3(1-1024)}{-3}+3=1-1024+3=\boxed{-1020}

It is a finite sum, so it is convergent.
