Write the equationequation in standard formX^2-1/X+1=2​

Mathematics
1 answer:
Anettt [7]3 years ago

Answer:

We start with the equation:

(x^2 - 1)/(x + 1) = 2

We want to rewrite this in standard form.

We can multiply both sides by (x + 1) to get:

((x^2 - 1)/(x + 1))*(x + 1) = 2*(x + 1)

x^2 - 1 = 2*(x + 1) = 2*x + 2

Now we can move all the terms to one side to get:

x^2 - 1 - 2 - 2*x = 0

x^2 - 2*x - 3 = 0

And this is a standard quadratic equation, that we can solve by using the Bhaskara's formula, this will give us the solutions:

x = \frac{-(-2) \pm \sqrt{(-2)^2 - 4*1*(-3)} }{2*1}  = \frac{2 \pm 4}{2}

Then the two solutions are:

x = (2 + 4)/2 = 3

x = (2 - 4)/2 = -1

Step-by-step explanation:

You can cut the shapes up to find the area.

Pink Figure: (not cut up)

A.

(13×7)-(4×1)=

91-4=

87 m²

P.

(1+1+4+4)+(7+13+7+13)=

10+40=

50 m

Yellow Figure:

A.

(14×4.5)+((14-9-3)×3)+((12-4.5-3)×14)=

(14×4.5)+(2×3)+(4.5×14)=

63+6+63=

132 m²

P.

14+4.5+3+3+3+4.5+14+4.5+9+3+9+4.5=

76 m
