Answer 1

Hey dear


Here your answer


$25 {x}^{2} + 3x + 9 = 0 \\ \\ \\ \\ \\ in \: equation \\ \\ \\ a = 25 \\ \\ b = 3 \\ \\ c = 9 \\ \\ \\ \\ \\ = > \: first \: we \: find \: delta \: d \\ \\ \\ \\ \: \: \: \: \: d = {b}^{2} - 4ac \\ \\ \: \: \: \: \: d = {3}^{2} - 4(25)(9) \\ \\ \: \: \: \: \: d = 9 - 900 = - 891 \\ \\ \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: d < 0 \\ \\ \\ \\ \: \: \: \: \: \: \: \: \: \: so \: factorise \: is \: not \: possible \: for \: this \: equation \\ \: \: \: \: \: \: \: \: \: bcoz \: d \: is \: small \: then \: to \: \: 0 \: (d < 0) \\ \\ \\ \\ \\ \\ \\ \: \: \: \: \: \: \: \: \: \: \: hope \: it \: helps \: you$
