How would you do number 12 and 15?
Gnesinka [82]

Answer:

x_1=x_2=-\dfrac{2}{3}

Step-by-step explanation:

For the quadratic equation ax^2+bx+c=0 the discriminant is defined as

D=b^2-4ac

and the quadratic formula for the roots gives us two roots:

x_1=\dfrac{-b-\sqrt{D}}{2a}

and

x_2=\dfrac{-b+\sqrt{D}}{2a}

For the equation 9x^2 +12x+4=0 use quadratic formula to find roots:

D=12^2-4\cdot 9\cdot 4=144-144=0

So,

x_1=x_2=\dfrac{-12\pm \sqrt{0}}{2\cdot 9}=-\dfrac{12}{18}=-\dfrac{2}{3}
