Given that g(x)=3x²-5x+7 find the following: <br> g(-x)

AURORKA [14]

G(x) = 3x² - 5x + 7
g(-x) = -(3x² - 5x + 7)
g(-x) = -3x² + 5x - 7

This equation cannot be solved because of a few reasons,

1. This equation didn't show that it equals to 0.
2. Even if it equals to zero, square root of a negative number cannot be solved.
(I will show you what I mean)

-3x² + 5x - 7
is the same as
3x² - 5x + 7
by shifting the equation,

for example,
1 - 3 = -2
shifting other side
2 = -1 + 3

using 3x² - 5x + 7 to solve,

$Solve\ using\ the\ formular\ \ \boxed{ x= { \frac{-b \pm \sqrt{b^2-4ac} }{2a} } }$
a = 3
b = -5
c = 7
$x= { \frac {-(-5) \pm \sqrt{ (-5)^2-4(3)(7) } }{2(3)} }$
$x= { \frac {5 \pm \sqrt{-59} }{6} }$

∴This equation cannot be solved.

Find the product 5 x (4 x 2)

Sedbober [7]

The product would be 40.

First, solve what is in parenthesis (). (4x2) is equal to 8. 5 x 8=40, so
5 x (4 x 2) = 40

So, strawberries cost 3.99 per pound and the apples cost 1.99 per pound.
So, strawberries cost more than apples. You can see that at 5 pounds and 3 pounds that strawberries will continue to exceed apples.
