What is the product of 6x – y and 2x – y + 2?

a=8x2 – 4xy + 12x + y2 – 2y
b=12x2 – 8xy + 12x + y2 – 2y
c=8x2 + 4xy + 4x + y2 – 2y
d=12x2 + 8xy + 4x + y2 + 2y

Option (B) is correct.

The product of 6x – y and 2x – y + 2 is

Step-by-step explanation:

Consider the given expressions 6x – y  and 2x – y + 2

We have to find the product of the above two given expressions,

multiply first term of first expression by each term of second expression and similarly  second term of first expression by each term of second expression

On solving, we get,

Solving further by combining like term, we get,

Thus, The product of 6x – y and 2x – y + 2 is

Hence, option (B) is correct.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
