Determine g(x + a) − g(x) for the following function.<br> g(x)=-5x^2-3x+2<br> g(x + a) − g(x)= ?

Sonja [21]

Easy
g(x+a)
sub x+a for every x in equation

g(x+a)=-5(x+a)^2-3(x+a)+2
g(x+a)=-5(x²+2xa+a²)-3x-3a+2
g(x+a)=-5x²-10xa-5a²-3x-3a+2
so now minus g(x)

g(x+a)-g(x)=
-5x²-10xa-5a²-3x-3a+2-(-5x²-3x+2)=
-5x²-10xa-5a²-3x-3a+2+5x²+3x-2=
-5x²+5x²-10xa-5a²-3x+3x-3a+2-2=
-10xa-5a²-3a

g(x+a)-g(x)=-5a²-10xa-3a

What is the value of x, when x2 + 5 = 21?

djverab [1.8K]

Hey there!

$\bold{x^2+5=21}$
<em>Firstly, subtract by the number $\bold{5}$ on each of your sides</em>
$\bold{x^2+5-5=21-5}$
$\bold{Cancel:5-5}$ because it gives us the result of $\bold{1}$
$\bold{Keep:21-5}$ because it equals: $\bold{16}$
$\bold{x^2=16}$
<em>Nextly, we have to take our square root </em>
$\bold{x=}$ ± $\bold{\sqrt{16}}$
<em>Solve the square root and you have found your answer</em>
<em> $\boxed{\boxed{\bold{Answer:x=4[or]x=-4}}}$ $\bold{\checkmark}$ </em>

Good luck on your assignment and enjoy your day!
