Simplify the expression
x^2+5x+4/x^2+3x-4*x^2-2x+1/x^2-1

Simplifying

(2x2 + -3x + 1)(x + -2)

Reorder the terms:

(1 + -3x + 2x2)(x + -2)

Reorder the terms:

(1 + -3x + 2x2)(-2 + x)

Multiply (1 + -3x + 2x2) * (-2 + x)

(1(-2 + x) + -3x * (-2 + x) + 2x2 * (-2 + x))

((-2 * 1 + x * 1) + -3x * (-2 + x) + 2x2 * (-2 + x))

((-2 + 1x) + -3x * (-2 + x) + 2x2 * (-2 + x))

(-2 + 1x + (-2 * -3x + x * -3x) + 2x2 * (-2 + x))

(-2 + 1x + (6x + -3x2) + 2x2 * (-2 + x))

(-2 + 1x + 6x + -3x2 + (-2 * 2x2 + x * 2x2))

(-2 + 1x + 6x + -3x2 + (-4x2 + 2x3))

Combine like terms: 1x + 6x = 7x

(-2 + 7x + -3x2 + -4x2 + 2x3)

Combine like terms: -3x2 + -4x2 = -7x2

(-2 + 7x + -7x2 + 2x3)

Step-by-step explanation:

false

step-by-step explanation:

whenever we assume a point on a plane then according to geometry it will definitely have 2 dimensions and if it assumed in space then it will have 3 dimensions.

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
