Question
Perform the operation.left bracket, 6, x, squared, plus, 2, x, right bracket, minus, left bracket, minus, 9, x, squared, minus, 10, x, right bracket(6x 2 +2x)−(−9x 2 −10x)
Solution
To perform the operation, you need to distribute the negative sign to each term in the second bracket. This will change the signs of each term in the second bracket.
The operation then becomes:
(6x^2 + 2x) - (-9x^2 - 10x)
= (6x^2 + 2x) + (9x^2 + 10x)
Then, you combine like terms:
= (6x^2 + 9x^2) + (2x + 10x)
= 15x^2 + 12x
So, (6x^2 + 2x) - (-9x^2 - 10x) = 15x^2 + 12x.
