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 =

i think this could be a possible answer (1 / 84) -1

good luck! : d

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
