Question

factories 100 - (x - 5)²​

Answer 1

Step-by-step explanation:

$100 - ( {x - 5)}^{2}$

$100 = - ( {x - 5)}^{2}$

$\sqrt{100} = - \sqrt{( {x - 5)}^{2} }$

$10 = - (x - 5)$

$10 = - x - 5$

$10 + 5 = - x$

$15 = - x$

$- x = 15$

$x = - 15$

Answer 2

Answer:

100 -(x-5)²

=10²-(x-5)²

Using identity a²-b²=(a+b)(a-b)

taking a as 10 and b as (x-5)

=(10+x-5){10-(x-5)}

=(10-5+x)(10-x+5)

=(5+x)(15-x)
