Question

what expression is equivalent to 3a - 2a x 4a +6a

Answer 1

Answer:

a (9 - 8 a x)

Step-by-step explanation:

Simplify the following:

3 a - 2 a x×4 a + 6 a

-2 a x×4 a = -2 a^2 x×4:

3 a + -2 a^2 x×4 + 6 a

-2×4 = -8:

3 a + -8 a^2 x + 6 a

Grouping like terms, 3 a - 8 a^2 x + 6 a = -8 a^2 x + (3 a + 6 a):

-8 a^2 x + (3 a + 6 a)

3 a + 6 a = 9 a:

-8 a^2 x + 9 a

Factor a out of -8 a^2 x + 9 a:

Answer: a (9 - 8 a x)

Answer 2

The expression that is equivalent to $3a - 2ax \times 4a +6a$ is: $\mathbf{a(9 - 8ax)}$

Given the expression:

$3a - 2ax \times 4a +6a$

To find an expression that is equivalent to the above expression, we will need to simplify the expression.

• Multiply

$3a - 2ax \times 4a + 6a\\\\3a - 8a^2x + 6a$

• Add like terms together

$3a + 6a - 8a^2x\\\\9a - 8a^2x$

Simplify the expression further by factoring out

$a(9 - 8ax)$

Therefore, the expression that is equivalent to $3a - 2a \times 4a +6a$ is $\mathbf{a(9 - 8ax)}$
