Question

factorise:x²+16x-225



.............important ​

Answer 1

Step-by-step explanation:

The factors of 225x² is 25x & 9x, difference of both the factors gives 16x

Solution:

$\implies$ $\sf{x^2+16x-225 }$

$\implies$ $\sf{ x^2+25x-9x - 225}$

$\implies$ $\sf{ x(x+25)-9(x+25)}$

By taking (x+25) as common,

$\therefore$ $\boxed{\sf{(x+25)(x-9) }}$
