By the zero product property, either (x^2 -4x + 4 = 0
<span>which easily factors into (x-2)(x-2) and thus gives two roots of 2 and 2 </span>
<span>or </span>
<span>( x^2 +3x -10) = 0 which also factors to give 2 and -5 </span>
<span>so all 4 roots : 2,2,2, -5 </span>
<span>and for your answer : { 2 and -5 } </span>
3+(-7)-2 = -6
4-16-2(2)= -12-4 = -16
Answer:
Step-by-step explanation:
<u>Use formula for continuous interest:</u>
- A =
, where r- interest rate, t- time in years
<u>If A = 3P, and r = 0.085 then the equation is:</u>
- ln 3 = 0.085t
- 1.099 = 0.085t
- t = 1.099 / 0.085
- t = 12.9 ≈ 13 years
the root of 196 is 14.......
The answer is 9. you start with 1+2 in the parenthesis and then divide 6 by 2. that gives you 3x3 which is 9
