What are the zeros of the quadratic function f(x) = 6x2 + 12x – 7?
zalisa [80]

we have

f(x) = 6x^{2} + 12x -7

To find the zeros equate the function to zero

6x^{2} + 12x -7=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

7= 6x^{2} + 12x

Factor the leading coefficient

7= 6(x^{2} + 2x)

Complete the square. Remember to balance the equation by adding the same constants to each side

7+6= 6(x^{2} + 2x+1)

13= 6(x^{2} + 2x+1)

Rewrite as perfect squares

13= 6(x+1)^{2}

(13/6)=(x+1)^{2}

square root both sides

x+1=(+/-)\sqrt{\frac{13}{6}}

x=-1(+/-)\sqrt{\frac{13}{6}}

x1=-1+\sqrt{\frac{13}{6}}

x2=-1-\sqrt{\frac{13}{6}}

therefore

the answer is

The zeros of the quadratic function are

x=-1+\sqrt{\frac{13}{6}} and x=-1-\sqrt{\frac{13}{6}}
