Answer 1

Step-by-step explanation:

BY USING FORMULA

plz mark. me as brilant

Answer 2

b= -4 ,a=3 , c= -10

x=-(-4) +- √(-4)^2 - 4*3*-10/2*3

x=4+- √16+120/6

x= 4 +- √136/6

x= 4 +- 11.66/6

positive part negative part

x= 4+11.66/6 x= 4 - 11.66/6

x=15.66/6 x= -7.66/6

x=2.61 x= -1.276

putting values of x=2.61 in given equestion

3*(2.62)^2 - 4*2.61 -10 =0

20.44 -10.44 -10 =0

0 = 0 proved

therefore values of x = 2.61
