Question

factorisation 2x²-5x-3=0
take into note the signs because they are (-)in both places and there are a lot of ans which had one of the signs as (+).but i require the squares with both (-) signs​

Answer 1

Step-by-step explanation:

$2x {}^{2} - 5x - 3 = 0 \\ 2x {}^{2} - 2x - 3x - 3 = 0 \\ 2x(x {}^{} - 1) - 3(x - 1) = 0 \\ (x - 1)(2 x - 3) = 0$

$x - 1 = 0 \\ x = 1$

$2x - 3 = 0 \\ 2x = 3 \\ x = \frac{3}{2}$
