A student wants to use the property (x - y) (x + y) = (x2 - y2) to find the product (26)(34). Which statement is true? The student should let z = 30 and y=2, then the product (26)(34) is 60 – 4.
The student should let I = 30 and y=2, then the product (26) (34) is 900 - 8.
The student should let I = 30 and y = 4, then the product (26) (34) is 60 - 8.
The student should let x = 30 and y = 4, then the product (26) (34) is 900 - 16.
