Question

ecuaciones cuadraticas 6x2+7x-3=0 4x2-3x-10=0 c. -10x2+17x-3=0 d. -7x2+11x-4=0

Answer 1

utiliza la formula cuadratica
6x∧2 + 7x - 3 = 0
a= 6     b=7     c= -3

-7 +- √7∧2 - 4(6)(-3)       -7 +- √49+72           -7+-√121      -7+-11
----------------------------- = -------------------- =    -------------- = ---------  =  1/3, - 3/2
         2(6)                                12                      12                12          dos sol
