Answer:

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

Explanation:

Given in the question the expression:

(x + 1) / (x² + x - 6) ÷ (x² + 5x + 4) / (x+4)

factorisation of (x² + x - 6) = (x-2)(x+3) by using quadratic equation

(x + 1) / (x-2)(x+3) ÷ (x² + 5x + 4) / (x+4)

Taking reciprocal to convert ÷ into ×

(x + 1) / (x-2)(x+3) x (x+4) / (x² + 5x + 4)

factorisation of (x² + 5x + 4) = (x+1)(x+4) by using quadratic equation

(x + 1) / (x-2)(x+3) x (x+4) / (x+1)(x+4)

cancel (x + 1) from both expression

1 / (x-2)(x+3) x (x+4) / (x+4)

cancel (x+4)

1 / (x-2)(x+3) Simplified form
