Sail with the equation by completing the square x^2+8x=-3

maxonik [38]

Answer:

The solutions are $x=-4(+/-)\sqrt{13}$

Step-by-step explanation:

we have

$x^{2} +8x=-3$

Complete the square. Remember to balance the equation by adding the same constants to each side

$x^{2} +8x+16=-3+16$

$x^{2} +8x+16=13$

Rewrite as perfect squares

$(x+4)^{2}=13$

square root both sides

$x+4=(+/-)\sqrt{13}$

$x=-4(+/-)\sqrt{13}$

Nookie1986 [14]

Answer: $4$

Step-by-step explanation:

Substitute the value of the variable into the equation and simplify.

I evaluate and found the exact value: 4

$( h -3 )2 \\h = 5$

If you want me to Find the Linearization at h=5: Use the formula $L(x)=f(a)+f'(a)$ $(x-a)$ to find the linearization.

Answer(Find the Linearization at h=5): $L(x)=2x-6$
