Question

factorisation of x2 + 10x + 25​

Answer 1

Answer:

x=-5

Step-by-step explanation:

x^2+10x+25= x^2+5x+5x+25

= X(X+5) + 5( X+5)

= (X+5) (X+5)

therefore

X+5 = 0

X = -5

Answer 2

Answer:

x² + 10x + 25 = x² + 2 (5) (x) + 5²

= ( x + 5 )²

[ (a + b )² = a² + 2ab + b² ]

= ( x + 5 ) ( x + 5 )
