whats the answer for xsquare+12x+20=0

The subject area is NOT 9th grade, but Math.

Factorizing we get (x+2) (x+10) = 0

so x = -2
or x = -10

To find the solution to the equation x^2 + 12x + 20 = 0, we can use the quadratic formula. The quadratic formula states that, for an equation of the form ax^2 + bx + c = 0, the solutions for x can be found using the formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

In this equation, a = 1, b = 12, and c = 20. Plugging these values into the quadratic formula, we get:

x = (-(12) ± √((12)^2 - 4(1)(20)))/(2(1))

Simplifying further:

x = (-12 ± √(144 - 80)) / 2

x = (-12 ± √64) / 2

x = (-12 ± 8) / 2

Now, we have two possible solutions:

x1 = (-12 + 8) / 2 = -2
x2 = (-12 - 8) / 2 = -10

So, the solutions to the equation x^2 + 12x + 20 = 0 are x = -2 and x = -10.
