Question

(9x²-3x-6)-(4x+5-2x²), Simplify the given expression.

Answer 1

$(9 {x}^{2} - 3x - 6) - (4x + 5 - 2 {x}^{2} ) \\ \\ \\ = > 9 {x}^{2} - 3x - 6 - 4x - 5 + 2 {x}^{2} \\ \\ \\ = > 9 {x}^{2} + 2 {x}^{2} - 3x - 4x - 6 - 5 \\ \\ \\ = > 11 {x}^{2} - 7x - 11$

Answer 2

BONJOUR,
❤ ❤ ❤ ❤

$(9x {}^{2} - 3x - 6) - (4x + 5 - 2x {}^{2} ) \\ \\ = 9x {}^{2} - 3x - 6 - 4x - 5 + 2x {}^{2} \\ \\ = 11x {}^{2} - 7x - 11$
