Question

How do you simplify 4x(x+2)?

Answer 1

Answer : 4x^2 + 8x

Step by step explanation :

$4x \times (x + 2)$

Multiply each term in the parenthesis by 4x.

$= > 4x \times x + 4x \times 2$

Calculate the product. If a term doesn't have an exponent it is considered that the exponent is 1.

$= > 4x {}^{1} \times x {}^{1} + 4x \times 2$

Multiply the terms with the same base by adding their exponents.

$= > 4x {}^{1 + 1} + 4x \times 2$

Add the numbers.

$= > 4x {}^{2} + 4x \times 2$

Calculate the product by multiplying the numbers.

$= > 4x {}^{2} + 8x$
