Answer:
-3 and 5
Step-by-step explanation:
f(n) = n² - 2n - 15
numbers whose product is -15 and sums up to -2 = -5 and 3
= n²- 5n+3n - 15
= n(n - 5) +3 (n - 5)
f(n) = (n + 3)( n - 5)
n + 3 = 0 n - 5 = 0
n = -3 n = 5
Roots = -3 and 5
Answer:
Divide both sides by 2
Step-by-step explanation:
We have the equation
2(x + 14) = 40
We divide both sides by 2
2(x + 14) = 40/2
x + 14 = 20
x = 20 - 14
x = 6
Therefore, the most helpful first step for solving Ravi's equation is: Divide both sides by 2
