Question

Expand and simplify (2x+1)(3x+6)

Answer 1

6x² + 15x + 6

Explanation:

Use FOIL:

Multiply the first terms:

(2x)(3x) = 6x²

Multiply 2x and 6:

(2x)(6) = 12x

Multiply 1 and 3x:

(1)(3x) = 3x

Multiply 1 and 6:

(1)(6) = 6

Then, add these all together:

6x² + 12x + 3x + 6

Add like terms:

6x² + 15x + 6 is the simplified expression

Answer 2

Explanation:

6x^2 + 12x + 3x + 6

6x^2 + 15x + 6
