Let the solutions be a and b.
a = -2; b = -10
a + b = -2 + (-10) = -12
ab = (-2)(-10) = 20
(x - a)(x - b) = 0
(x - (-2))(x - (-10)) = 0
(x + 2)(x + 10) = 0
x^2 + 10x + 2x + 20 = 0
x^2 + 12x + 20 = 0
-h = 12
h = -12
4k = 20
k = 5
Answer:
1
Step-by-step explanation:
1 times anything equals the opisite number but in this case you are multiplying 1 by itself 999999999999 times and that equals 1
The answer is B because the x doesn’t repeat in that one.
