~~~~2x^2 =-10 * 19\\\\\implies 2x^2 = -190\\\\\implies x^2 = -\frac{190}2\\\\\implies x^2 = -95\\\\\implies x = \pm√(-95)\\\\\implies x = \pm √(-1)√(95)\\\\\implies x = \pm i√(95)

Answer:

x=0 or x=−95

Explanation:

Step 1: Simplify both sides of the equation.

−190x=2x²

Step 2: Subtract 2x² from both sides.

−190x−2x²=2x²−2x²

−2x²−190x=0

Step 3: Factor left side of equation.

(−2x)(x+95)=0

Step 4: Set factors equal to 0.

−2x=0 or x+95=0

x=0 or x=−95
