Question

(17y+8b2-11)-(70-9b2+18y)​

Answer 1

(17y+8b²-11)-(70-9b²+18y)=17y+8b²-11-70+9b²-18y=-y+17b²-81

Answer 2

To simplify the expression (17y + 8b^2 - 11) - (70 - 9b^2 + 18y), you can distribute the negative sign inside the parentheses and then combine like terms. Here's the step-by-step simplification:

1. Distribute the negative sign:

(17y + 8b^2 - 11) - (70 - 9b^2 + 18y) = 17y + 8b^2 - 11 - 70 + 9b^2 - 18y

2. Now, combine like terms:

(17y - 18y) + (8b^2 + 9b^2) - (11 - 70) = -1y + 17b^2 + (-59)

So, the simplified expression is:

-1y + 17b^2 - 59
