The quadratic formula is the result of completing the square for ax^2+bx+c=0 when a,b, and c are unknown values. This result is:
x=(-b±√(b^2-4ac))/(2a), we have x^2-x-2=0 so
x=(1±√(1+8))/2
x=(1±√9)/2
x=(1±3)/2
x=-1 and 2
Answer:
For 21 picks, there are 6 orange
Step-by-step explanation:
orange: green : total
2 5 2+5
2 5 7
If there are 21 picks, we need to divide by 7 to see how many times we need to multiply
21/7 = 3
Multiply everything by 3
orange: green : total
2*3 5*3 7*3
6 15 21
For 21 picks, there are 6 orange
