Solve by factoring 2x^3-9x^2+10x=0 with full steps
Strike441 [17]
X(2x²-9x+10)=x(2x-5)(x-2)=0.
x=0 is one solution.
2x-5=0 and x-2=0 give us the solutions x=5/2 and x=2.
So x=0, 2 or 5/2.

Use the image below to answer the following parts.
12345 [234]

Answer:

Step-by-step explanation:

Part A

Since, the given angles are formed at a point are on a straight line, sum of these angles will be 180°.

Part B

(3x - 5)° + (4x + 2)° + (2x + 3)° = 180°

9x = 180

x = 20

Part C

m∠ADB = (3x -  5)°

             = (3×20 - 5)°

             = 55°

m∠DBK = (4x + 2)°

             = (4×20 + 2)°

             = 82°

m∠KBC = (2x + 3)°

             = (2×20 + 3)°

             = 43°
