Factor completely 4xy − 7x + 20y − 35.
(x + 5)(4y − 7)
(x − 5)(4y + 7)
(x − 5)(4y − 7)
(x + 5)(4y + 7)

A)

Step-by-step explanation:

Given expression:

To factor the given expression completely.

Solution:

In order to factor the expression, we will factor in pairs.

We will factor the G.C.F of the terms in the pairs.

G.C.F. of and can be given as:

Thus, G.C.F. =

G.C.F. of and can be given as:

Thus, G.C.F. =

The expression after factoring the G.C.F. pairs is given as:

Taking G.C.F. of the whole expression as is a common term.

The expression is completely factored.
