Consider the equation
Ira Lisetskai [31]

The solution to the original equation is 1, 1/6

<h3>Solving equation</h3>

Equations are expressions separated by mathematical operations.

Given the equation below

x/x − 1 = 6x + 1/x − 1

From the given expression, the least common denominator is x -1

Multiply both sides by x-1 to have;

x = 6x(x-1) +1

Expand

x = 6x^2-6x + 1

Equate to zero

6x^2-6x-x + 1 = 0

6x^2-7x +1= 0

The resulting quadratic equation in general form is 6x^2-7x +1 = 0

Factorize

6x^2 -6x-x + 1 = 0

Group the result

6x(x-1)-1(x-1) = 0

(6x-1)(x-1) = 0

6x - 1 = 0 and x -1 = 0

x = 1 and 1/6

Hence the solution to the original equation is 1, 1/6

Physical and chemical changes
SCORPION-xisa [38]

Answer:

Physical and chemical changes can occur in matter. The look of material changes as a result of a physical change. Physical changes are sometimes known as phase changes. When materials change phase, they transition from solid to liquid, liquid to gas, or some other combination. If you mix materials together and see fire, bubbles, or a change in color, you might be able to see a chemical shift.

Find the Two Values that x can have if X^2 -10=26​
Zolol [24]

Answer:

x1= -6 x2=6

Step-by-step explanation:

x^2-10 = 26

x^2 = 26 +10

x^2 = 36

x = sqrt(36)

x = -6 or x = 6 because both 6 and -6 squared are equal to 36
