Question

Resuelve:. ayudaaaaaa
(A+B)-(C+D)
A) 2x - 5x² + 7x - 8
B) 12x - x + 6x2 - 1
C) -3x + x² + 20x - 3
D) 2x - 5x2 + x3 - 10​

Answer 1

A) 2x - 5x² + 7x - 8 =

4x² = 8

x² = 8/4

x² = 2

X = √2

B) 12x - x + 6 x 2 - 1

11x + 11

X = 11/11

X= 1

C) - 3x + x² + 20x - 3

18x² = 3

X² = 3/18

X² = 0.17

X = 0.41

D) 2x - 5 x 2 + X . 3 - 10

3x - 10 + 3 - 10

3x = 17

X = 17/3

X = 5.67

Entonces:

(A + B) - (C + D)

(√2 + 1) - (0.41 + 5.67)

Quite los paréntesis (Calcular la suma):

√2 + 1 - 6.08

Calcule:

√2 - 5.08
