Question

4x×(x-5)-3×(x²+3x-1)+2×(2x-1)=x²____
care este rezolvarea?
×=inmultire
x=partea literala​

Answer 1

4x · (x - 5) - 3 · (x² + 3x - 1) + 2 · (2x - 1) = x²

~~~~~~~~~~~~~~~~~

x = ?

~~~~~~~~~~~~~~~~~

4x · (x - 5) - 3 · (x² + 3x - 1) + 2 · (2x - 1) = x²

4x² - 20x - 3x² - 9x + 3 + 4x - 2 = x²

x² - 25x + 1 = x²

25x = 1

x = $\frac{1}{25}.$
