X² - 6x + 4 = 0 solve and show work. ...?

ycow [4]

The answer is 3 + √5 and 3 - √5.

This is quadratic equation: x² - 6x + 4 = 0
The general quadratic equation is ax² + bx + c = 0
Our equation can be rewritten: 1x² + (-6)x + 4 = 0
So, in our equation we have: a = 1, b = -6, c = 4

Now, x can be calculated using the formula: $x_{1,2}= \frac{-b+/- \sqrt{ b^{2}-4ac } }{2a}$
$x_{1,2} =\frac{-(-6)+/- \sqrt{ (-6)^{2}-4*1*4 } }{2*1} = \frac{6+/- \sqrt{36-16} }{2} = \frac{6+/- \sqrt{20} }{2} =\frac{6+/- \sqrt{4*5} }{2}= \\ 
=\frac{6+/- \sqrt{4}* \sqrt{5} }{2} =\frac{2*3+/- 2\sqrt{5} }{2}= \frac{2(3+/- \sqrt{5}) }{2} =3+/- \sqrt{5}$

From here:
$x_{1} =3+ \sqrt{5} \\ 
x_{2} =3- \sqrt{5}$

-7p-4>26p-94 solve for p

Maslowich

Answer:

$\large\boxed{p$

Step-by-step explanation:

$-7p-4>26p-94\qquad\text{add}\ 7p\ \text{to both sides}\\\\-7p+7p-4>26p+7p-94\\\\-4>33p-94\qquad\text{add 94 to both sides}\\\\-4+94>33p-94+94\\\\90>33p\qquad\text{divide both sides by 33}\\\\\dfrac{90}{33}>\dfrac{33p}{33}\\\\\dfrac{30}{11}>p\to p$
