Pls find the zeros

in 10th level

x = - 3, x =

Step-by-step explanation:

Given

x² + 2 x - 6

To calculate the zeros equate to zero

x² + 2 x - 6 = 0 ( add 6 to both sides )

x² + 2 x = 6

One way is to use the completing the square method

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

x² + 2 x + ()² = 6 + ()²

x² + 2 x + 2 = 6 + 2

(x + )² = 8

Take the square root of both sides

x + = ± = ± 2

subtract from both sides

x = - ± 2

x = - - 2 = - 3, or

x = - + 2 =

the square root of what number? if you add that, then someone will probably answer the question.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
