Write the equation with both x= 8 and x= -8 as solution

nlexa [21]

Answer:

$y = x^2 - 64$

Step-by-step explanation:

Hello!

We can use the factored form of a Quadratic to find an equation with 8 and -8 as our solution.

<h3>Factored Form: $y = a(x - h)(x - k)$ </h3>

The value in each parenthesis should be 0. So 8 and -8 can be flipped and used for h and k.

$y = a(x - h)(x - k)$
$y = a(x - 8)(x+ 8)$

This will give roots 8 and -8 for x.

$y = 1(x - 8)(x + 8)\\$
$y = x^2 - 64$

A possible equation is $y = x^2 - 64$ .

Solve the system of equations -x-2y=0 and -x+y=6 by combining the equations

Elden [556K]

Answer:

x=-4 and y=10

Step-by-step explanation:

Use the second equation to make y=x+6

sub y=x+6 into the first equation

-x-2*(x+6)=0

-x-2x-12=0

-3x-12=0

3x=-12

x=-4

Now sub x=-4 into the second equation

-(-4)+y=6

y=6+4

y=10
