Question

3х²+11х+6=0

СРОЧНО!!!!!!!​

Answer 1

${3x}^{2} + 11x + 6 = 0 \\ {3x}^{2} + 9x + 2x + 6 = 0 \\ 3x \times (x + 3) + 2(x + 3) = 0 \\ (x + 3) \times (3x + 2) = 0 \\ x + 3 = 0 \\ 3x + 2 = 0 \\ x = - 3 \\ x = - \frac{2}{3} \\ {x}^{1} = - 3, \: {x}^{2} = - \frac{2}{3}$

Answer 2

Объяснение:

+9x+2x+6=0

3x×(x+3)+2(x+3)=0

(x+3)×(3x+2)=0

x+3=0

3x+2=0
