Answer:

$\large { \boxed{\sf x = -4}$

Explanation:

Original Expression:

$\rightarrow \sf x + 5 = 5 - 0 - 6 + 2$

Subtract '5' from both sides:

$\sf \rightarrow x+5-5=5-0-6+2-5$

Simplify the following:

$\sf \rightarrow x=-0-6+2$

Add/Subtract integers:

$\sf \rightarrow x=-4$

What are the zeros of the quadratic function f(x) = 6x^2 + 12x – 7?

irinina [24]

6x^2 + 12x – 7 = 0

Use the quadratic formula:

$x= \frac{-b +/- \sqrt{b^2 -4ac} }{2a}$

$\frac{-12+/- \sqrt{ 12^{2} -4(6)(-7)} }{12} = \frac{-12+/-17.66}{12}$

x = 0.47 and x = -2.47
