Question

a + b whole square minus 5 into a plus b whole square minus 6

Answer 1

Hello,

${(a + b)}^{2} - 5 \times {(a + b)}^{2} - 6 \\ {a}^{2} + {b}^{2} + 2ab - 5( {a}^{2} + {b}^{2} + 2ab) - 6 \\ {a}^{2} + {b}^{2} +2ab - {5a}^{2} - {5b}^{2} - 10ab - 6 \\ - {4a}^{2} - {4b}^{2} - 8ab - 6 \\ - 2( {2a}^{2} + {2b}^{2} + 4ab + 3)$

Hope it helps!
