Question

9x elevado a 2+22x+4 igual a 10x

Answer 1

9^2+22x+4=10x
22x-10x= -4-9^2
12x= -4-81
x= 85/12

Answer 2

Então: 9x^2 + 22x + 4 = 10x 9x^2 + 22x - 10x + 4 = 0 9x^2 + 12x + 4 = 0 a = 9 b = 12 c = 4 Calculando ∆: ∆ = b^2 - 4ac ∆ = 12^2 -4.9.4 ∆ = 144 - 144 ∆ = 0 As raízes: x = (-b +- √∆)2a x = (-12 +- √0)/2.9 x = (-12)/18 x = -12/18 x = -2/3
