Use the quadratic formula to find the solutions to the equation x^2-3x+1=0

Gnom [1K]

Answer:

$x_{1}=\frac{+3+\sqrt{5} }{2}\\\\x_{2}=\frac{+3-\sqrt{5} }{2}$

Step-by-step explanation:

Using:

$x=\frac{-b+-\sqrt{b^{2}-4*a*c} }{2*a}$

we will have two solutions.

x^2-3x+1=0

So, a=1 b=-3 c=1

$x_{1}=\frac{+3+\sqrt{-3^{2}-4*1*1} }{2*1}\\\\x_{2}=\frac{+3-\sqrt{-3^{2}-4*1*1} }{2*1}$

We have two solutions:

$x_{1}=\frac{+3+\sqrt{5} }{2}\\\\x_{2}=\frac{+3-\sqrt{5} }{2}$

How find a ratio of the area of a circle and a square

ladessa [460]

Answer:

CIRCLE : CIRCLE

Ratio of area is the scale factor squared. So find the radii of the two circles, square both values, and simplify the ratio.

SQUARE : SQUARE

Ratio of area is the scale factor squared, So find the side lengths of the two squares, square both values, and simplify the ratio.

SQUARE : CIRCLE

Using the formulas A = s*s and A = pi*r^2, find the areas of the circle and the square. Then simplify the ratio.
