Find a X given the following equation:
(x+3)2+(2x−3)2=5x(x−53)
To solve this problem, let's expand and simplify each side of the given equation:
- Step 1: Expand the left side:
- Expand (x+3)2=x2+6x+9
- Expand (2x−3)2=4x2−12x+9
Combine them to get x2+6x+9+4x2−12x+9=5x2−6x+18.
- Step 2: Expand the right side:
- Expand 5x(x−53)=5x2−3x
- Step 3: Set the equations from both sides equal and simplify:
5x2−6x+18=5x2−3x
- Step 4: Subtract 5x2 from both sides:
−6x+18=−3x
- Step 5: Simplify to:
−6x+3x=−18
or equivalently −3x=−18
- Step 6: Solve for x:
x=−3−18=6
Therefore, the solution to the problem is x=6.
