What is the form of the Difference of Squares identity?

Mathematics
1 answer:
Feliz [49]3 years ago
3 0
The difference identity of two squares can be stated as:

a² - b² = (a + b)(a -b)

i.e. the product of sum of two numbers with the difference of two numbers. This can be easily proved.

For example, Let a = 4 and b = 3

so, a² - b² = 16 - 9 = 7

a + b = 4 + 3 = 7
a - b =4 - 3 = 1

(a + b )(a - b) = 7 x 1  = 7

Thus,

a² - b² = (a+b)(a-b)

So, option C gives the correct answer

What is the value of r+s+t when r = 26 , s= -12 , t= -8?
Len [333]
R + s + t

Plug in the values.
r = 26
s = -12
t = -8

r + s + t
26 + (-12) + (-8)
26 - 12 - 8
14 - 8
6

Remember these rules:

a + (+b) = a + b
a + (-b) = a - b
a - (+b) = a - b
a - (-b) = a + b
