1. Nyatakan persamaan persamaan berikut dalam bentuk umum persamaan kuadrat!
a. 6x^2+4x-5 = 4x^2+9x
b. 14y^2-7y+14 = 5y^2-7y-11
c. 2p(p+6)-8 = p^2-3p+6
a. 6x^2+4x-5 = 4x^2+9x
b. 14y^2-7y+14 = 5y^2-7y-11
c. 2p(p+6)-8 = p^2-3p+6
6x²+4x-5 = 4x²+9x
6x²-4x²+4x-9x-5 = 0
2x²-5x-5 = 0
b)
14y²-7y+14 = 5y²-7y-11
14y²-5y²-7y+7y+14+11 = 0
9y²+25 = 0
c)
2p(p+6)-8 = p²-3p+6
2p²+12p-8 = p²-3p+6
2p²-p²+12p+3p-8-6 = 0
p²+15p-14 = 0
