salam sir i have a questions reguarding sings in maths why is it like that when we use identities both trig and algebra identities we do not use negative sign like for example expand cos(x-60)

[@lanaali8534]

Salam sir I think in the last question we can’t say if (a-1)x + b-2a+8 =0 then a-1 =0 and b-2a+8 = 0 it’s not a must that every term is 0 in order for the sum to be zero for example -3+3 is zero Instead we can compare dividend with the divisor*quotient to find a and b
