Question

3x2 + 5x + 2 by splitting the middle term method

Answer 1

$\huge\boxed{\underline{\bf { \red S \green O \pink L \blue U \orange T \purple I \red O \pink N \green{..}}}}$

$\large\mapsto \sf {3x}^{2} + 5x + 2$

$\large\mapsto \sf {3x}^{2} + 3x + 2x + 2$

$\large\mapsto \sf3x(x + 1) + 2(x + 1)$

$\large\mapsto \sf(3x + 2)(x + 1)$

Answer 2

Answer:

Step-by-step explanation:

3x²+5x+2=0

3x²+x(3+2)+2=0

3x²+3x+2x+2=0

3x(x+1)+2(x+1)=0

(3x+2)(x+1)=0

3x+2=0 3x=-2 x=-2/3

x+1=0 x=-1
