The quadratic equation, in its standard form is: ax2 + bx + c = 0 where a, b and c are constants and a is not zero.
ax2 + bx + c = 0
Without an equality sign the given terms of an algebraic expression can't be classed as an equation and so therefore a solution is not possible.
It is: x2-10x+21 = 0 and the value of x is 3 or 7 when solved
There are many ways: one is to factorise. If the quadratic is written as ax2 + bx + c then, if b2 = 4ac, the quadratic is a perfect square. It is (x - b/2a)2

ax2 + bx + c = 0
The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.

George E. Forsythe has written: 'What is a satisfactory quadratic equation solver?' 'Finite-difference methods for partial differential equations' 'How do you solve a quadratic equation?'

The coefficient for oxygen is 1, and so is not written. The equation is already balanced.
Yes that about sums it up.
It is: x2-10x+21 = 0 and the value of x is 3 or 7 when solved
It is: 3x2-5x-2 = 0 and the value of x is -1/3 or 2 when solved
