(x+5) (x+6) (x+7) kindly tell me plzzzzzzzzzzzzz​

Answer 1

$\bigstar$ Question:

Find the product of :

• (x+5) (x+6) (x+7)

$\bigstar$ Given:

• (x+5) (x+6) (x+7)

$\bigstar$To find:

The product of:

• (x+5) (x+6) (x+7)

$\bigstar$ Solution:

$(x+5) (x+6) (x+7)$

$= [(x)(x) + (x)(6) + (x)(5) + (6)(5) ](x + 7)$

$= [ {x}^{2} + 6x + 5x + 30](x + 7)$

$= [ {x}^{2} + 11 x + 30](x + 7)$

$= [( {x}^{2})(x) + ( {x}^{2} )(7) + 11x(x) + (11x) \times 7 + 30(x) + (30)(7)]$

$= ( {x}^{3} + {7x}^{2} + {11x}^{2} + 77x + 30x + 210 )$

$= {x}^{3} + {18x}^{2} + 107x + 210$

$\bigstar$Answer:

Therefore, the answer is :

${x}^{3} + {18x}^{2} + 107x + 210$

Answer 2

Answer:

$(x + 5)(x + 6)(x + 7)$

$=( {x}^{2} + 5x + 6x + 30)(x + 7)$

$=( {x}^{2} + 11x + 30)(x +7 )$

$= {x}^{3} + 11 {x}^{2} + 30x + 7 {x}^{2} + 77x + 210$

$= {x}^{3} + 18 {x}^{2} + 107x + 210$
