Question

write in standard form.
x^2+7x+12=0

Answer 1

You can either use the quadratic formula or the splitting method, whichever you find easier.
By the splitting method:

The given equation can be expressed as:
\[x ^{2} + 4x + 3x + 12 = 0\]
\[x( x+4) + 3(x+4) = 0\]
\[(x+3) (x+4) = 0\]
Therefore, x = -4 or x = -3
