Resolver los siguientes ecuaciones a)2x + 5 • (3 - 2) = x + 10 b) 2•x3 + 6 = 8 c) 90 + 2x = 3•(x - 7).
ax² + bx + c = 0
En resumen
A)2x + 5 • (3 - 2) = x + 10 = 2x + 5 ×(1) = x + 10 = 2x + 5 = x + 10 2x - x = 10 - 5 X = 5 b) 2•x3 + 6 = 8 = 2x³ = 8 - 6 = 2x³ = 2 X³ = 2 / 2 X³ = 1 X = ³√1 X = 1 c) 90 + 2x = 3•(x - 7) 90 + 2x = 3x - 21 90 + 21 = 3x - 2x 111 = x X = 111.
A)2x + 5 • (3 - 2) = x + 10 = 2x + 5 ×(1) = x + 10 = 2x + 5 = x + 10
2x - x = 10 - 5
X = 5
b) 2•x3 + 6 = 8 = 2x³ = 8 - 6 = 2x³ = 2
X³ = 2 / 2
X³ = 1
X = ³√1
X = 1
c) 90 + 2x = 3•(x - 7)
90 + 2x = 3x - 21
90 + 21 = 3x - 2x
111 = x
X = 111.
