Question

me ajuda por favor porfavor​

Answer 1

$\frac{4 {a}^{2} - 7a + 3 }{4a - 3} = 0$

$\frac{4 {a}^{2} - 3a - 4a + 3}{4a - 3} = 0$

$\frac{a \times (4a - 3) - (4a - 3)}{4a - 3} = 0$

$\frac{(4a - 3) \times (a - 1)}{4a - 3} = 0$

$a - 1 = 0$

$a = 1$

Answer 2

$\frac{ {4a}^{2} - 7a + 3 }{4a - 3}$

$\frac{4 {a}^{2} - 3a - 4a + 3}{4a - 3}$

$\frac{a \times (4a - 3) - (4a - 3)}{4a - 3}$

$\frac{(4a - 3) \times (a - 1)}{4a - 3}$

$a - 1$
