Answer:
the answer for this question is c
Answer:
x = StartFraction negative 2 plus or minus StartRoot 2 squared minus 4(4)(negative 1) EndRoot Over 2(4) EndFraction
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form

is equal to

in this problem we have

so



substitute in the formula

therefore
x = StartFraction negative 2 plus or minus StartRoot 2 squared minus 4(4)(negative 1) EndRoot Over 2(4) EndFraction
Try this solution:
1. if 1st number is 'x', the 2d number is 'y', then it is possible to make up the system of two equation according to the condition:

2. one number is 11, another number is 10.
You wouldn’t because 3 is the base number and cannot be simplified anymore
2 * (2a + b) + 8 = 4a + 2b + 8
------------------------------------------
A. =
B. =
C. ≠ 4* (a + b + 2) = 4a + 4b + 8
D. =
