Question
\(x^2+4x +4=0\)
Solution
Quadratic Formula Method
1
\( \text{Compare } x^{2} + 4 x + 4 = 0 \text{ with the standard quadratic equation } ax^2 +bx+c = 0 \text{ and find the values of a, b, and c } \)
\( a = 1 \text{ , } b = 4 \text{ , } c = 4 \)
2
Calculate the value of the discriminant (D)
\( D = 0 \)
3
Determine the nature of the roots
The roots are real and equal
4
\( \text{ Apply the quadratic formula and find the roots of } x^{2} + 4 x + 4 = 0 \)
\( \text{The roots are } -2 \text{ and } -2 \)
