2x(x+4)=(x-3)(x-3) how to make it in standard form
Answer (1)
Step 1 . Expand both sides of the equation. Expand the left side: 2x(x+4)=2x² + 8x.Expand the right side:(x-3)(x-3) = x² 3x-3x + 9 = x²- 6x + 9. The equation becomes: 2x² +8x = x² - 6x+ 9Step 2 . Move all terms to one side of the equation. Subtract \(x^{2}\) from both sides: 2x² - x² + 8x = -6x + 9 Add \(6x\) to both sides: x² + 8x + 6x=9. Subtract 9from both sides: x² + 14x-9=0 Solution The standard form of the equation is x² + 14x-9 = 0
