By looking at it, I can tell the second expression is greater due to a a large postive number that's being added to it. Let's solve.

-34-3=-37+39=2

So, -34-3+39 is greater.

Solve the equation x2 + x = 12.
Otrada [13]

please give brainliest

Let's solve your equation step-by-step.

x2+x=12

Step 1: Subtract 12 from both sides.

x2+x−12=12−12

x2+x−12=0

Step 2: Factor left side of equation.

(x−3)(x+4)=0

Step 3: Set factors equal to 0.

x−3=0 or x+4=0

x=3 or x=−4

Answer:

x=3 or x=−4
