Pertanyaan

(x-3)(6x+11)=2(7-4x)
Persamaan linear satu variabel

Answer 1

6x2 + 11x - 18x - 33 = 14 - 8x
6x2 + 11x - 18x + 8x = 14 + 33
6x2 + x = 47

Answer 2

(x-3)(6x+11)=2(7-4x)

(x.6x) +(x.11) + (-3.6x) + (-3.11) = 14 -8x

6x^2 + 11x -18x -33 = 14 -8x

6x^2 -7x -33 +8x = 14

6x^2 +x -33-14=0

6x^2 + x - 47 =0

6x^2+x=47

x(6x+1) =47
