hello

the quadratic equation given is


x^2-4x+3=0

now let's find two factors to the equation and proceed to solve the equation.

to do this, i'll write down the standard form of a quadratic equation out


ax^2+bx+c=0

to solve this by factorization, we need to find two numbers that when they're multiplied will give us the value of c but when added will give the value of b

in this case, our value of b = -4 and c = 3

two numbers that will give us the desired value are (-1, -3)


x^2-4x+3=(x-1)(x-3)

the factorized form of the equation would be (x - 1)(x - 3)
