Which of the following is a solution of x2 + 6x = −22?

−3 ± isquare root of 13
−3 ± isquare root of 52
−6 ± isquare root of 13
−6 ± isquare root of 52

answer asap with an

C) 3 - i√13

Step-by-step explanation:

x² - 6x = -22

x² - 6x + (-6/2)² = -22 + (-6/2)²

x² - 6x + 9 = -22 + 9

(x - 3)(x - 3) = -13

x - 3 = ± √-13

x - 3 = ± i√13

x = 3 ± i√13

x = 3 + i√13 & x = 3 - i√13

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
