Question

(3x - 2)3 +43x+37 = (x + 5) + x2 (26x - 70)​

Answer 1

Respuesta:

x_1=191-√41889/104, x_2=191+√41889/104

Forma alterna

x_1=0.131, x_2=3.8

Explicación paso a paso:

Operamos.

(3x-2)3+43x+37=(x+5)+2x(26x-70)

9x-6+43X+37=x+5+52X^2-140x

52x+31=-139x+5+52x^2

52x+31+139x-5-52x^2=0

191x+26-52x^2=0

-52x^2+191x+26=0

(-1)-52x^2+191x+26=0(-1)

52x^2-191x-26=0

Usamos ecuación general.

x=-(-191)+-√(-191)^2-4(52)(-26)/2(52)

x=191+-√36481+5408/104

x_1=191+√41889/104 y x_2=191-√41889/104
