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.
That the discriminant of the quadratic equation must be greater or equal to zero for it to have solutions. If the discriminant is less than zero then the quadratic equation will have no solutions.

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?'

Yes that about sums it up.

The coefficient for Cl₂ is 1. If not written explicitly in a chemical equation, a coefficient of 1 is understood to be present.
It is: 3x2-5x-2 = 0 and the value of x is -1/3 or 2 when solved
