Question

the sums of (2x + 7) (4x - 7) and (6x+ 4).​

Answer 1

Given:

Three expressions -

• (2x + 7)
• (4x - 7)
• (6x + 4)

What To Find:

We have to find

• The sum of the given three expressions.

Solution:

(2x + 7) + (4x - 7) + (6x + 4)

Remove the brackets,

⇒ 2x + 7 + 4x - 7 + 6x + 4

Rearrange the like terms,

⇒ 2x + 4x + 6x + 7 - 7 + 4

Here,

• First like terms = 2x + 4x + 6x
• Second like terms = 7 - 7 + 4

Solve the first like terms,

⇒ 12x + 7 - 7 + 4

Solve the second like term,

⇒ 12x + 4

Final Answer:

∴ Thus, the sum of the three expressions is 12x + 4.
