1. (3x+10)²
2. (-2+2n)²
3. (-n -7)²
4. (6a+a+1)²

the formula
For positive (a+b)=a²+2ab+b²
For negative (a+b)=a²-2ab+b²

HELP ME PLS!



Example.
(4x²+2)
(4²)(x²)+2(4x²)(2)+(2)²
4x4=16 (x²)+8x2(2)+2

Problem:

  • 1.) (3x+10)²
  • 2.) (-2+2n)²
  • 3.) (-n -7)²
  • 4.) (6a+a+1)²

Formula:

  • For positive (a+b)=a²+2ab+b²
  • For negative (a+b)=a²-2ab+b²

Solution 1:

  • 1.) (3x+10)²

  • ⟶ (3x+10)(3x+10)
  • ⟶ (3x)² + 2(3)(10) + (10)²
  • ⟶ 9x²+60x+100

Answer:

[tex]\quad\quad\quad\boxed{\red{\sf{⟶ 9x²+60x+100}}}[/tex]

Solution 2:

  • 2.) (-2+2n)²

  • ⟶ (-2+2n)(-2+2n)
  • ⟶ (-2)² + 2(-2)(2n) + (2n)²
  • ⟶ 4 - 8n + 4n²

Answer:

[tex]\quad\quad\quad\boxed{\red{\sf{⟶ 4 -8n+4n²}}}[/tex]

Solution 3:

  • 3.) (-n -7)²

  • ⟶ (-n -7)(-n -7)
  • ⟶ (-n)² + 2(-n)(-7) + (-7)²
  • ⟶ n²+14n+49

Answer:

[tex]\quad\quad\quad\boxed{\red{\sf{⟶ n²+14nx+49}}}[/tex]

Solution 4:

  • 4.) (6a+a+1)²

  • ⟶ (6a+a+1)(6a+a+1)²
  • ⟶ (6a)² + 2(6a)(a) + (1)²
  • ⟶ 49a² +14a+1

Answer:

[tex]\quad\quad\quad\boxed{\red{\sf{⟶ 49a²+14a+1}}}[/tex]
