Expanding Algebraic Expression

Write the expanded form of the expression.

5​(6x - 2​)

Answer explanation

To expand the expression 5(6x - 2), distribute 5 to both terms inside the parentheses. This gives us 30x - 10. Therefore, the correct expanded form is 30x - 10.

2(2x + 1) =

• 4x + 1

• 2x + 2

• 5x

• 4x + 2

2(x + 3) + 4 =

• 2x + 6 + 4

• 2x + 6

• 2x + 10

Expand (x + 5)(x + 4)

• x² + 9x + 20

• x² + 20x + 20

• 5x² + 20

• x² + 6x + 9

(x+2)(x+3)

• x² + 5x + 6

• x² + 6x + 5

• x² + 7x + 5

• x² + 6x + 6

(x-7)(x+3)

• x²-3x-21

• x²+4x-21

• x²-4x+21

• x²-4x-21

(3x+2)(2x +3)

• 6x² + 6x + 6

• 5x² + 11x + 6

• 6x² + 13x + 6

• 6x² + 13x + 5

Expand (3x + 2)(x+4)

• 3x² + 11x + 8

• 3x² + 6x + 8

• 3x² + 12x + 8

• 3x² + 14x + 8

Expand and simplify the following quadratic expression... (x + 4)²

• x² + 16

• x² + 8x + 16

• x² + 4x + 16

• x² + 16x + 8

(x-8)(x+1)

• x²-9x-8

• x²-7x-8

• x²-7x+8

• x²+9x-8
