These can be very helpful when you're stuck on a problem and don't know how to Solve 2x2 x 15.
2x 2 + x – 15 = 2 ( x - 5 2) ( x + 3) (2) The critical numbers are x - 5 2 = 0 or x + 3 = 0. The critical numbers are x = 5 2 or x = – 3. Divide the number line into three intervals. ( - ∞, - 3), ( - 3
Algebra Solve for x 2x^2+x=15 2x2 + x = 15 2 x 2 + x = 15 Subtract 15 15 from both sides of the equation. 2x2 + x−15 = 0 2 x 2 + x - 15 = 0 Factor by grouping. Tap for more steps (2x−5)(x
