What is the positive solution to the equation 0 = –x2 + 2x + 1? Quadratic formula: x = –2 + 2 – 1 + –1 +
Georgia [21]

The standard form of a quadratic equation is :

ax² + bx + c = 0

And the quadratic formula is:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a} .

So, first step is to compare the given equation with the above equation to get the value of a, b and c.

So, a = -1, b = 2 and c = 1.

Next step is to plug in these values in the above formula. Therefore,

x=\frac{-2\pm\sqrt{(2)^2-4*(-1)*(1)}}{2*(-1)}

=\frac{-2\pm\sqrt{4+4}}{-2}

=\frac{-2\pm\sqrt{8}}{-2}

=\frac{-2\pm\sqrt{4*2}}{-2}

=\frac{-2\pm\sqrt{4}*\sqrt{2}}{-2}

=\frac{-2\pm2*\sqrt{2}}{-2}

=-\frac{-2}{-2} \pm\frac{2\sqrt{2}}{-2}

So, x =1 \pm\sqrt{2} .

Answer:

B. First term = 5, Common difference = -3

Step-by-step explanation:

The first term is f(1) = 8 - 3(1) = 8 - 3 = 5.

The common difference is the coefficient of  n.  Another way to see this is to compute the second term, f(2) = 8 - 3(2) = 8 - 6 = 2.  The second term is 3 less than the first.  The common difference is -3.

The sequence goes 5, 2, -1, -4, ...
