What are the zeros of the quadratic function f(x) = 2x2 – 10x – 3?

Ipatiy [6.2K]

Answer:

$x = \frac{ 5 \ + \ \sqrt{31}}{2} \ , \ x = \frac{ 5 \ - \ \sqrt{31}}{2}$

Step-by-step explanation:

$2x^2 - 10x - 3 = 0 \\\\a = 2 \ , b = - 10 \ , \ c = - 3 \\\\x = \frac{-b^2\ \pm \ \sqrt{b^2 - 4ac}}{2a}\\\\x = \frac{10 \ \pm \sqrt{(-10)^2 - ( 4 \times 2 \times -3)} }{2 \times 2}\\\\x = \frac{10 \ \pm \sqrt{(100 - ( -24 )} }{4}\\\\x = \frac{10 \ \pm \sqrt{(100 + 24 } }{4}\\\\x = \frac{ 10 \ \pm \sqrt{124}}{4}\\\\x = \frac{ 10 \ \pm \sqrt{4 \times 31}}{4}\\\\x = \frac{ 10 \ \pm \sqrt{2^2 \times 31}}{4}\\\\x = \frac{ 10 \ \pm2 \sqrt{31}}{4}\\\\x = \frac{ 5 \ \pm\sqrt{31}}{2}\\\\$

$x = \frac{ 5 \ + \ \sqrt{31}}{2} \ , \ x = \frac{ 5 \ - \ \sqrt{31}}{2}$

Answer:

Step-by-step explanation:

Any negative (when there is only one of them) will be the least. negatives are smaller than positives.

A fraction is less than a whole number. So far what you have is

___ ___ 3/15 , - 24/30

So now which is bigger? 11 or 11.5

Which would you rather have? 11 dollars or 11 dollars and 50 cents. 11.5>11

The correct order is 11.5 11 3/15 - 24/30

Which expression is equivalent to -1/4 x + 1/2?

Anna71 [15]

The expression is given by:

$-\frac{1}{4}x+ \frac{1}{2}$

So we need to find an equivalent equation for this problem. Then, we will apply some mathematical rules:

Extracting the common factor 1/4, then:

$\frac{1}{4}(-x+2})$

Or extracting the common factor -1/4, then:

$-\frac{1}{4}(x-2})$

So, comparing these solutions with the answers about, there is no any answer that matches.
