Question

Solve the following quadratic equation using the quadratic formula and then choose the correct solution set. 6x^2-7x+2=0

a. {-1/2,2/3}
b. {1/2,3/2}
c.{1/2,2/3}

Answer 1

Explanation:

hello :

6x²-7x+2=0 quadratic equation when : a =6 b = -7 c =2

∆= b²-4ac

∆= (-7)²- 4(6)(2)= 49-48 =1

X1= (-b+√∆)/2a = (7+1)/12 = 8/12 =2/3

X2= (-b-√∆)/2a = (7-1)/12 = 6/12 =1/2

the solution is : {1/2,2/3}.....answer : C
