​

Answer 1

Answer:

QUESTION:−

factorise :-

{x}^{2} + 25x - 100x

2

+25x−100

ᴀɴsᴡᴇʀ

➪ {x}^{2} + 25x - 100 = 0➪x

2

+25x−100=0

➪ {x}^{2} + 20x + 5x - 100 = 0➪x

2

+20x+5x−100=0

➪x(x + 20) - 5(x + 20)➪x(x+20)−5(x+20)

➪(x - 5)(x + 20)➪(x−5)(x+20)

➪x = 5 \: and \: x = - 20➪x=5andx=−20

Answer 2

x² + 25x + 100 = 0

x² + 20x + 5x + 100 = 0

x(x + 20) + 5(x + 20) = 0

(x + 20) (x + 5) = 0

x = -20 , x = -5

Hope it helps!!

Thank you ✌️
