What is the next step in solving 0 = x2 + 6x – 10 by completing the square, after you cut 6 in half?

Lynna [10]

Answer:

see below

Step-by-step explanation:

0 = x^2 + 6x – 10

Add 10 to each side

10 = x^2-6x

Take the coefficient of x

-6

Divide by 2

-6/2 =-3

Square it

(-3)^2 =9

Add 9 to each side

10+9 = x^2-6x+9

We use -3 for the square term

19 = (x-3)^2

Take the square root of each side

±sqrt(19) = x-3

Add 3 to each side

3±sqrt(19) = x

Solve for x. Use the completing the square method. x² + 8x = 7

AfilCa [17]

Divide the coefficient by 2 then square the quotient.
Add the result to both sides of the equation.

$x^2 + 8x = 7$
$x^2 + 8x + (\frac{8}{2})^2 = 7 + (\frac{8}{2})^2$
$x^2 + 8x + 4^2 = 7 + 4^2$
$x^2 + 8x + 16 = 7 + 16$
$x^2 + 8x + 16 = 23$

Now, factor the left-hand side.

$x^2 + 8x + 16 = 23$
$(x + 4)^2 = 23$

Take the square root of both sides.

$(x + 4)^2 = 23$
$x + 4 = \sqrt{23}$
$x = -4$ ± $\sqrt{23}$
