7x(x+2) +21(x+2)

(7x+21)(x+2)

Answer 2

hlo mate ✌️

${7x^2} + {35x} + 42$

${7x^2} + {35x} + {42} = 0$

Dividing each term by 7:

${</strong><strong>x^</strong><strong>2</strong><strong>} + {5x} + {</strong><strong>6</strong><strong>} = 0$

${</strong><strong>x^</strong><strong>2</strong><strong>} + {</strong><strong>2</strong><strong>x</strong><strong> </strong><strong>+</strong><strong> </strong><strong>3</strong><strong>x</strong><strong>} + {6} = 0$

${x</strong><strong>(</strong><strong>x</strong><strong> </strong><strong>+</strong><strong> </strong><strong>2</strong><strong>)</strong><strong>} + </strong><strong>{</strong><strong>3</strong><strong>(</strong><strong> </strong><strong>x</strong><strong> </strong><strong>+</strong><strong> </strong><strong>2</strong><strong> </strong><strong>)</strong><strong>}</strong><strong> = 0$

[tex] {x +3} + {x +2} = 0[/tex]

case 1 :

x + 2 = 0

x = -2

case 2 :

x + 3 = 0

x = -3

Hope it helps ❣️
