Solve by completing the square<br> -x^2+8x-6=0
Svetllana [295]
-x² + 8x - 6 = 0
x = <u>-(8) +/- √((8)² - 4(-1)(-6))</u>
                     2(-1)
x = <u>-8 +/- √(64 - 20)</u>
                 -2
x = <u>-8 +/- √(44)
</u>              -2<u>
</u>x = <u>-8 +/- 2√(11)
</u>              -2
x = <u>-8 + 2√(11)</u>         x = <u>-8 - 2√(11)
</u>             -2                            -2<u>
</u>x = 4 - √(11)             x = -8 + √(11)

Given f(x) = 5x - 6 and g(x) = x2 - 5x + 6, find the function (f + g)(x). Use the ^ key for the exponent. Enter your answer as t
sesenic [268]
The answer is x².

f(x) = <span>5x - 6
</span>g(x) = x²<span> - 5x + 6

(f + g)(x) = f(x) + g(x)
              = </span>5x - 6 + x² - 5x + 6
              = x² + 5x - 5x + 6 - 6

Provide the first six terms of the following sequence:<br><br> t1=81 tn=1/3tn-1
Andrews [41]

We get tne n-th term with: tn=1/3tn-1

We know that the first term is t1=81, so 81=1/3t*1-1

81=1/3t-1

82=1/3t

82*3t=1

3t=1/82

t=1/82*3=1/246

The second term is: 1/

2*(1/246)*2)-1

We get the third term by replacing n with 3 and so on...
