Question

Using identity find the product
(x + 5) (x+2)
​

Answer 1

$\huge{\orange{\underline{\underline{\mathfrak{SoluTion:}}}}}$

Given,

☞ (x+5)(x+2)

$\boxed{\sf{(a+b)(a+c) = a²+a(b+c)+bc}}$

$→\;{\bf{x²+x(5+2)+(5×2)}}$

$→\;{\bf{x²+x7+10}}$

◕➜ $\fbox\red{\sf{x²+7x+10}}$

Hope It Helps You ✌️

Answer 2

$\huge\rm\purple{answer~࿐}$

$\sf{ }$

$\bf{{\underline{To~solve}}:}$

$\sf{~~~~~ (x+5)(x+2)}$

$\bf{{\underline{Identity}}:~(x+a)(x+b)=x^{2}+(a+b)x+ab}$

$\sf{\mapsto x^{2}+(5+2)x+(5×2)}$

$\sf{\mapsto {\purple{\underline{\boxed{\bf x^{2}+7x+10}}}}}$
