c)4x^2-7x-60=0​

Answer 1

Respuesta:

a)x=3.24695076-17.24695076

b)x=-5-9

c)x=4.84559504-3.095504

Answer 2

${x}^{2} - x - 56 = 0$

$(x - 8)(x + 7) = 0$

$x - 8 = 0$

$x = 0 + 8$

$x = + 8$

$x + 7 = 0$

$x = 0 - 7$

$x = - 7$

${x}^{2} + 14x + 45 = 0$

$(x + 5)(x + 9) = 0$

$x + 5 = 0$

$x =0 - 5$

$x = - 5$

$x + 9 = 0$

$x = 0 - 9$

$x - 9$

$4 {x}^{2} - 7x - 60 = 0$

$(2x + 12)(2x - 5) = 0$

$2x + 12 = 0$

$2x = - 12$

$x = - 12 \div 2$

$x = - 6$

$2x - 5 = 0$

$2x = 5$

$x = 5 \div 2$

$x = 2.5$
