Question

Which of the numbers 4, 5 or 6 is a solution to (n+3)(n-2) = 36​

Answer 1

Answer:

6 is the correct solution

Step-by-step explanation:

(4+3)(4-2)=14. so no

(5+3)(5-2)=24. so no

(6+3)(6-2)=36. yes

Answer 2

Answer:

n(n-2) + 3(n-2) = 36

n²-2n+3n-6 = 36

n²+n-6=36

n²+n=42

n²+7n-6n-42

n(n+7)-6(n+7)

n = 6 or n= -7
