Question

) Resolver la ecuacion
5(2x² - 6x + 4) + 4(5x²- 5 + 6x) = 0​

Answer 1

5(2x² - 6x + 4) + 4(5x²- 5 + 6x) = 0​

10x² - 30x + 20 + 20x²- 20 + 24x = 0

10x² + 20x² - 30x + 24x  + 20 - 20  = 0

30x²- 6x = 0

6x(5x - 1) = 0

6x = 0              5x - 1 = 0

x = 0/6             5x = 1

x = 0                   x  = 1/5

CS = (0 ; 1/5)
