What equation shows x^2+6x-6=0 rewritten by completing the sqaure

Mathematics
1 answer:
arlik [135]3 years ago
6 0

Answer:

(x + 3)² = 15

Step-by-step explanation:

Given

x² + 6x - 6 = 0 ( add 6 to both sides )

x² + 6x = 6

To complete the square

add (half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = 6 + 9

(x + 3)² = 15

Ket [755]

Take note that the vine was 3.6 ft and now it is 2.1 times as long.

So since is it 2.1 times as long it will be multiplied by 3.6.

3.6(2.1)= 7.56

So it is 7.56 ft long, rounded it is 7.6 ft
