Question

-find the product (2x+9) and 8x²y


-simplify by using (a+b)( a-b )=a²- b² 67×73​

Answer 1

8x2y*(2x+9)  

= 16x3y + 72x3y

= 72+16x3y

= 88x3y

explanation

first, multiply the first term with the second term first number

8x²y *  2x

then multiply the first term with the second term second number

8x²y *  9

then you get 16x3y + 72x3y

the you add the terms and you get

88x3y
