How to put -3x(4-6x) in distributive property

Rashid [163]

Answer:

-12x+18x²

Step-by-step explanation:

Given: $-3x(4-6x)$

Distributive property of multiplication under which a number is multiplied by the sum of two number, the first number can be distributed to both of those number.

∴ $-3x(4-6x)$

solving it by using distributive property

= $(-3x\times 4)-(-3x\times 6x)$

= $-(12x) + 18x^{2}$

Opening parenthesis

= $-12x+18x^{2}$

Hence, -12x+18 $x^{2}$ is the result after using distributive property.
