4sin x=2sin x + √3
4sin x-2sinx=√3
2sin x=√3
sinx=√3/2
x=arcsin √3/2=π/3 + 2Kπ U 2π/3+2Kπ
Sol: π/3 + 2Kπ U 2π/3+2Kπ ; K∈Z
π/3+2Kπ=60º+360ºk
2π/3+2Kπ=120º+360ºK

Answer:
x=-2 or x=7
Step-by-step explanation:
X²-5X-14=0 find the factors of -14x² which is -7x and +2x
X² -7x + 2x - 14 = 0 factorize
x(x-7) + 2(x-7) = 0
(x+2)(x-7) =0
x+2 = 0 or x-7= 0
x=-2 or x=7
