The rational expression fraction numerator x squared plus 6 x minus 7 over denominator x squared plus 9 x plus 14 end fraction s
Thepotemich [5.8K]

The simplification of rational expression (x²+6x-7)/(x²+9x+14) gives

(x-1)/(x+2). 

<h3>What is factorisation?</h3>

A polynomial or integer is simply resolved into components that, when multiplied together, produce the original or starting polynomial or integer.

  • The factorization method allows us to simplify any algebraic and quadratic equation by representing the equations as that of the product or factors rather than by expanding the brackets.
  • Any equation can have an integer, a variable, or the algebraic expression itself as a factor.

The given expression is -

= (x²+6x-7)/(x²+9x+14)

Factorising both numerator and denominator;

= {x+7x-x-7} / {x+7x+2x+14}

= {x(x+7)-(x+7)} / {x(x+7)+2(x+7)}

= {(x+7)(x-1)} / {(x+7)(x+2)}

Cancel the (x+7),

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

Therefore, the simplification of the given equation is (x-1)/(x+2).

To which linear equations is the coordinate a solution?
never [62]

The linear equation y = -x - 2  and y = 2x + 13 form the solution (-5, 3)

<h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the y intercept.

Given the coordinate (-5, 3) as a solution.

The linear equation y = -x - 2 satisfies this this equation because 3 = -(-5) -2

Also, the linear equation y = 2x + 13 satisfies this this equation because 3 = 2(-5) + 14
