Question

2a³+7(x²-x+1)(x+1)=?

Answer 1

2a(3)+7(x(3)+1)
2a(3)+7x(3)+7

Answer 2

To simplify the expression 2a³ + 7(x² - x + 1)(x + 1), follow these steps:

Step 1: Expand the second term using the distributive property. Step 2: Combine like terms, if any.

Let's proceed with the calculations:

Step 1: Expand the second term (x² - x + 1)(x + 1) (x² - x + 1)(x + 1) = x²(x) + x²(1) - x(x) - x(1) + 1(x) + 1(1) = x³ + x² - x² - x + x + 1 = x³ + 1

Step 2: Substitute the expanded term back into the original expression: 2a³ + 7(x² - x + 1)(x + 1) = 2a³ + 7(x³ + 1)

And that's the simplified expression: 2a³ + 7(x³ + 1)
