Troyz881 :

Just take the square root of both sides!

JustKarl ☕ :

Was für ein Aufwand. 0 und -18. Der geklammerte Ausdruck muss 9 oder -9 ergeben. Fertig.

Lá Diêu Bông :

(x + 9)² = 7² (x + 9) = 7 & (x +9) = - 7 x = - 2 & x = - 16

Cento i Ximet :

a=x+9 a^2=49=7•7 a=+-7 a=7 -> x=-2 a=-7 -> x=-16

Silvia9098 :

-2

@moh.m :

+ or - 2

TARIK EL3AJMAWI :

( x+ 9 )² = 49 √ ( x + 9 )² = ± √ 49 x + 9 = 7 | x + 9 = - 7 x = 7 - 9 | x = - 7 - 9 ((( x = - 2 ; x = - 16 )))

Mohamadou diawo Ba :

(x+9)^2=49 x+9=7 or x+9=-7 x=-2 or x=-16

⁵ Hải ™ :

(x+9)²-7²=0 (x+9-7)×(x+9+7)=0 x=-2 or x=-16

Đức Nguyễn Văn :

49=7²=(-2+9)² or (-16+9)² (x+9)²=(-2+9)² =>x=-2 or (x+9)²=(-16+9)² => x=-16
