Question

Operación 1: (x+5)(X)=234
Operación 2: (3x)(x)=1,083
Operación 3: (x)(x-3)=550
Operación 4: (x)(x/2)=800
SI NO SABEN PLIS NO RESPONDAN. ME GASTAN PUNTOS >:v

Answer 1

Operación 1:(x+5)(X)=234

(5 + x) * X = 234

X (5 + x) = 234

(5 * X + x * X) = 234

(5X + xX) = 234

5X + xX = 234

-234 + 5X + xX = 234 + -234

-234 + 5X + xX = 0

Operación 2: (3x)(x)=1,083

(3x)(x)-(1.083)=0

3xx-1.083=0

3xx=1.083

x=1.083/1

x=1.083

Operación 3: (x)(x-3)=550

x² - 3x - 550 = 0

(x - 25)(x +22) = 0  

x - 25 = 0

x = 25

x + 22 = 0

x = -22

Operación 4: (x)(x/2)=800

x²=1600

x=√1600

x=40
