Answer 1

Answer:

ok that's good and answer

Answer 2

ANSWER :-

$We \: have \: to \: Factorize \: = 3 {x}^{2} + 10x + 7 = 0$

$Now, \\ \\ 3 {x}^{2} + 10x + 7 = 0 \\ \\ = > 3 {x}^{2} + 3x + 7x + 7 = 0 \\ \\ = > 3x(x + 1) + 7(x + 1) = 0 \\ \\ = > (3x + 7)(x + 1) = 0 \\ \\ = > 3x + 7 = 0 \: \: \: \: \: \: \: \: \: \: and \: \: \: \: \: \: x + 1 = 0 \\ \\ = > x = \frac{ - 7}{3} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: and \: \: \: \: \: \: x = - 1$

$the \: factorisation \: of \: \\ 3 {x}^{2} + 10x + 7 = 0 \: is \: (3x + 7)(x + 1)$
