What are the possible values of x in x2 + 3x + 3 = 0?

e-lub [12.9K]

To solve a quadratic equation like $ax^2+bx+c=0$ , you can use the quadratic formula

$x_{1,2} = \cfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

In your case, $a = 1, b = c = 3$ , so the formula becomes

$x_{1,2} = \cfrac{-3\pm\sqrt{(-3)^2-4\cdot 1\cdot 3}}{2\cdot 1}$

We can simplify the expression:

$x_{1,2} = \cfrac{-3\pm\sqrt{9-12}}{2} = \cfrac{-3\pm\sqrt{-3}}{2}$

Since -3 is negative, its square root is computed as

$\sqrt{-3} = \sqrt{-1\cdot 3} = \sqrt{-1}\sqrt{3} = \sqrt{3}i$

So, the solutions are

$x = \cfrac{-3+i\sqrt{3}}{2} \text{ or } x = \cfrac{-3-i\sqrt{3}}{2}$

Step-by-step explanation:

$\tt{} \frac{ \sqrt[3]{60} }{ \sqrt[3]{36} }$

$\tt{} \frac{ \sqrt[3]{5} }{ \sqrt[3]{3} }$

$\tt{} \frac{ \sqrt[3]{5} }{ \sqrt[3]{3} } \times \frac{ \sqrt[3]{ {3}^{2} } }{ \sqrt[3]{ {3}^{2} } }$

$\tt{} \frac{ \sqrt[3]{5} \sqrt[3]{ {3}^{2} } }{ \sqrt[3]{3} \sqrt[3]{ {3}^{2} } }$

$\tt{} \frac{ \sqrt[3]{5 \times {3}^{2} } }{ \sqrt[3]{3 \times {3}^{2} } }$

$\tt{} \frac{ \sqrt[3]{5 \times 9} }{ \sqrt[3]{ {3}^{3} } }$

$\tt{} \frac{ \sqrt[3]{45} }{3}$

$\tt{}1.18563$

the spoke of a wheel reaches from the center of the wheel to its rim with circumference of a rim is 42 inches how long each spok

Virty [35]

The constant π is defined as the ratio of the circumference of a circle with respect to its diameter, mathematically:

π=C/d which can be rearranged to

C=πd

Since the diameter is equal to twice the radius of the circle, ie d=2r

C=2πr dividing both sides by 2π gives you:

r=C/(2π), the "spoke" in our problem is equal to the radius of a circle, and we are told that C=42in so:

r=42/(2π) in

r=21/π in

r≈6.68 in (to nearest hundredth of an inch)
