Question

(x-2)*2-(3-x)*2=1

pdta: *** significa elevado

Answer 1

$(x-2)^{2} - (3-x) ^{2} = 1$

$(x^{2} -4x +4) - (9-6x+ x^{2} )= 1$

$x^{2} -4x +4 -9 + 6x - x^{2} = 1$

-4x +6x - 5 = 1

2x = 1+5

2x = 6

x= 6/2

x=3

Answer 2

Resolver.

(a - b)² = a² - 2ab + b²

(x - 2)² - (3 - x)² = 1
x² - 2(x)(2) + 2² - (3² - 2(3)(x) + x²) = 1
x² - 4x + 4 - ( 9 - 6x + x²) = 1
x² -4x + 4 - 9 + 6x - x² = 1
x² - x² - 4x + 6x + 4 - 9 = 1
2x - 5 = 1
2x = 1 +5
2x = 6
x = 6/2
x = 3

Respuesta.
x = 3
