Answer:
The answer to your question is below
Step-by-step explanation:
1) k² + 3k - 40 = 0
(k + 8)(k - 5)= 0
2.- x²- 10x = 0
x(x - 10) = 0
3.- y² + 18y + 80 = 0
(y + 10)(y + 8) = 0
4.- h² - 4h = 0
h(h - 4) = 0
5.- n²- 11n = 0
n(n - 11) = 0
6.- p² - 13p + 40 = 0
(p - 8)(p - 5) = 0
7.- h² - 7h - 60 = 0
( h -12)(h + 5) = 0
8.- h² + 7h - 44 = 0
(h + 11)(h - 4)= 0
9.- r² + 6r = 0
r(r + 6) = 0
10.- k² - 10k = 0
k (k - 10) = 0
