Which two values of x are roots of the polynomial below 4x^2-6x+1

goblinko [34]

Step-by-step explanation:

Just apply the quadratic formula $x=\frac{-b \left \ {{+} \atop {-}} \right. \sqrt{b^{2}-4ac} }{2a}$

Your equation is $4x^2-6x+1$
Every quadratic equation follows the general form $ax^2+bx+c$

In this case $a=4,b=-6,c=1$
Substitute into the quadratic formula:
$x=\frac{-(-6) \left \ {{+} \atop {-}} \right. \sqrt{(-6)^{2}-4(4)(1)} }{2(4)}\\x=\frac{6 \left \ {{+} \atop {-}} \right. \sqrt{36-16} }{8}\\x=\frac{6 \left \ {{+} \atop {-}} \right. \sqrt{20} }{8}$ Now take note that the square root of any number gives a (+) and (-) result, so two different answers
$x=\frac{6 + \sqrt{20} }{8} ,and\\x=\frac{6 - \sqrt{20} }{8}$ are the answers

#1 How long would it take to count to one billion, reciting the numbers one after another? First, write a guess into

4vir4ik [10]

Answer:

Step-by-step explanation:

In that case, it would take you a billion seconds. Dividing that by 60 (and leaving the remainder in second form), we find that it would take 16,666,666 minutes and 40 seconds.

I think it that, I'm not sure. I hope this help
