Question

the area of a rectangular garden is given by the trinomial x^2+x-30. What are the possible dimensions of te rectangle?

Answer 1

Answer: 5cm and (-)6cm

Explanation:

X² + x - 30

Using factorization method,

Factors are

(X-5) , (x+6)

X² + x - 30 = 0

X² -5x + 6x -30 = 0

(X-5) + (x+6) = 0

X-5 = 0 or x + 6 = 0

X = 5 or x = -6
