We can write this equation as:

A quadratic equation is in the form of
......[1] where a,b ,c are the coefficient and x is the variable,
the solution of the equation is given by;

On comparing given equation with equation [1] we get;
a = 3 , b = -4 and c =10
So, the solution of the given equation is given by;

or

or
[∴
Simplify:

therefore, the roots of the given equation are; 
Answer:
If you take 32 percent of a number and get 64, then what is that number? In other words, you know that 32 percent of a number is 64 and you want to know what that initial number is.

Answer:
True ; false ; False ; true
Step-by-step explanation:
Equation 1:
7 20 + □ = 19 20
19 / 20 - 7/20
(19 - 7) / 20
12/ 20 = 3/5
Equation 2:
□ + 3 10 = 3 15
3/5 + 3/10
(6 + 3) / 10 = 9/10
Equation 3:
1 2 + 2 3 = □
1/ 2 + 2/3
(3 + 4) / 6
7 / 6
Equation 4:
1 10 + 1 2 = □
1/10 + 1/2
(1 + 5) / 10
6 / 10 = 3/5
