Answer 1

Step-by-step explanation:

this is the answer I have posted with attachment

Answer 2

$9 {x}^{2} + 30x + 25 = 0$

=>

$9 {x}^{2} +15x + 15x+ 25 = 0$

=>

$3x(3x + 5) +5(3x + 5)= 0$

=>

This is the factorised equation

$(3x + 5) \times (3x + 5) = 0$

=>

${(3x + 5)}^{2} = 0$

=>

$3x + 5 = 0$

=>This is the root of the equation.

$x = \frac{ - 5}{3}$
