Find the solution set of the following quadratic equations using the quadratic formula.
oksian1 [2.3K]

Answer:

<h3>                1)  x_1=\dfrac{7+\sqrt{13}}2\,,\quad x_2=\dfrac{7-\sqrt{13}}2</h3><h3>                2)   x_1=-\dfrac13\,,\quad x_2=-3    </h3>

Step-by-step explanation:

<h3>1)</h3>

x^2 - 7x + 9 = 0\quad\implies\quad a=1\,,\ b = -7\,,\ c=9\\\\x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(-7)\pm\sqrt{(-7)^2-4\cdot1\cdot9}}{2\cdot1}=\dfrac{7\pm\sqrt{49-36}}2\\\\x_1=\dfrac{7+\sqrt{13}}2\,,\quad x_2=\dfrac{7-\sqrt{13}}2

<h3>2)</h3><h3>3x^2 + 10x=-3\\\\3x^2+10x+3=0\quad\implies\quad a=3\,,\ b =10\,,\ c=3\\\\x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-10\pm\sqrt{10^2-4\cdot3\cdot3}}{2\cdot3}= \dfrac{-10\pm\sqrt{100-36}}6\\\\x_1=\dfrac{-10+\sqrt{64}}6=\dfrac{-10+8}6=-\dfrac13\,,\qquad x_2=\dfrac{-10-8}6=-3</h3>

Sarah needs 3 feet of fabric for a project she is working on, but the store only sells the fabric in meters. One meter of fabric
Virty [35]

Answer:

The 3 feet fabric will cost $ 1.09728 almost $ 1.10

Step-by-step explanation:

First we will find out how many meters 3 feet will be.

1 feet = 0.3048 meters

She needs 3 feet of fabric

3 *1 feet = 3* 0.3048  ( multiplying both sides by 3)

3 feet = 0.9144 meters

Using the unitary method we will find the cost of 3 feet of fabric

1 meter costs $ 1.20

0.9144 *1 meter costs $ 1.20 * 0.9144  ( multiplying both sides by 0.9144)

0.9144  meter = $ 1.09728

The 3 feet fabric will cost $ 1.09728 almost $ 1.10
