Weegy: When you multiply and simplify (x + 4)(x^2 - 3x + 2) you get the result of x^3 + x^2 - 10x + 8. User: Two runners start 30 kilometers apart and run toward each other. They meet after 3 hours. One runner runs 2 kilometers per hour faster than the other runner. What rate do they run?
2 km/hr and 4 km/hr
3 km/hr and 5 km/hr
5 km/hr and 7 km/hr
4 km/hr and 6 km/hr Weegy: 4 km/hr and 6 km/hr. User: Solve for x.
2(x - 4) = 6(x + 2)
-2
-1
-5
4 Weegy: The answer is 5. User: Completely factor the polynomial.
100x 2 - 25
25(2x + 1)(2x - 1)
(10x + 5)(10x - 5)
(20x + 5)(5x - 5)
25(4x2 - 1) (More)
