Respuesta :
Using factorization, the missing factor is (a + 6) of the given quadratic equation a² + 8a + 12 = 0.
What is a quadratic equation?
It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
Given
The quadratic equation is a² + 8a + 12 = 0
The factor of the quadratic equation will be.
[tex]\begin{aligned}a^2 + 8a + 12 &=0 \\a^2 + 6a + 2a +12 &= 0\\(a+ 6)(a +2 ) &= 0\\\end{aligned}[/tex]
Thus, the missing factor is (a + 6).
