Question

Resolva as seguintes equações abaixo:

x²+11x = 16x - 6

Answer 1

$x^{2} +11x = 16x - 6 x^2+11x-16x+6=0 \\ x^2-5x+6=0 \\ \\ \Delta=(-5)^2-4.1.6=25-24=1 \\ \\ x=\frac{5+-1}{2} \\ \\ x_1=\frac{5-1}{2}=2 \\ \\ x_2=\frac{5+1}{2}=3$

Answer 2

x²+11x=16x-6
x²-5x+6
Δ=b²-4ac
Δ= 25- 24
Δ=1

x= -b + -√Δ/2a
x= 5 + - 1/2

x'= 3
x''= 2

S: [2,3]
