Question

2/5(5x-2)(4x-1-x/2)=19/2​

Answer 1

Step-by-step explanation:

$= > \frac{2}{5} (5x - 2)(4x - 1 - \frac{x}{2} ) = \frac{19}{2} \\ = > (20 {x}^{2} - 5x - \frac{5 {x}^{2} }{2} - 8x + 2 + x) = \frac{19}{2} \times \frac{5}{2} \\ = > (20 {x}^{2} - 12x- \frac{5 {x}^{2} }{2} + 2) = \frac{95}{4} \\ = > \frac{40 {x}^{2} - 24x - 5 {x}^{2} + 4 }{2} = \frac{95}{4} \\ = > 35 {x}^{2} - 24x + 4 = \frac{95}{2} \\ = > 2(35 {x}^{2} - 24x + 4) = 95 \\ = > 70 {x}^{2} - 48x + 8 = 95 \\ = > 70 {x}^{2} - 48x -87 = 0 \\ \red{\mathfrak{\underline{\large{hope \: it \: helps \: you }}}} \\ \green{\mathfrak{\underline{\large{mark \: me \: brainliest}}}}$
