Answer 2

ANSWER:

To simplify:

• 3(2x²+3)+4(3x²-5)

Solution:

⇒ 3(2x²+3)+4(3x²-5)

First, we distribute the numbers written outside the brackets to the inner ones.

⇒ (3*2x²) + (3*3) + (4*3x²) + (4*-5)

⇒ 6x² + 9 + 12x² - 20

Now, we rearrange the terms, so that like terms come together.

⇒ 6x² + 12x² + 9 - 20

Solving the like terms,

⇒ 18x² - 11
