Question

pls solve this(x+5)(x-5)

Answer 1

Answer:

x= 5 , -5

Step-by-step explanation:

(x+5)(x-5)

(x²-5²) ( identity)

x²-25

x²= 25

x= ✓25

x= +5 or -5 ( As we are squaring 25)

OR

(x+5)(x-5)

x+5 = 0

x= -5 (bring 5 to the other side)

x-5=0

x= 5 (bring 5 to the other side so that negative 5 becomes positive 5)

Answer 2

Answer:

= 5

Step-by-step explanation:

(x+5)(x-5)

(a+b)(a-b) = a²-b²

x²-5²

x²-25 = 0

x² = 25

x = √25

x = 5
