Question

Which will result in a difference of squares? (negative 7 x 4)(negative 7 x 4) (negative 7 x 4)(4 minus 7 x) (negative 7 x 4)(negative 7 x minus 4) (negative 7 x 4)(7 x minus 4)

Answer 1

An expression is defined as a set of numbers, variables, and mathematical operations. The expression that will result in the difference in the squares is (7x+4)(7x-4).

What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The difference between the squares can be written as,

$a^2-b^2=(a+b)(a-b)$

The expression that will result in the difference in the squares will be

$(7x+4)(7x-4)=(7x)^2-(4)^2$

Thus, the expression that will result in the difference in the squares is (7x+4)(7x-4).
