(3a^4-2a^2+5a-10)-(2a^4+4a^2+5a-2)
=3a^4-2a^2+5a-10-2a^4-4a^2-5a+2)
= a^4-6a^2-8

the project to remedy is: (3a4-2a2+5a-10)-(2a4+4a2+5a-2) Multiply a and three Multiply a and a million The a in simple terms receives copied alongside. the reply is a a three*a evaluates to 3a Multiply 4 and 3a Multiply a million and a The a in simple terms receives copied alongside. a three*a*4 evaluates to 12a Multiply a and a couple of Multiply a and a million The a in simple terms receives copied alongside. the reply is a a 2*a evaluates to 2a Multiply 2 and 2a Multiply a million and a The a in simple terms receives copied alongside. a 2*a*2 evaluates to 4a 3*a*4-2*a*2 evaluates to 8a Multiply a and 5 Multiply a and a million The a in simple terms receives copied alongside. the reply is a a 5*a evaluates to 5a 3*a*4-2*a*2+5*a evaluates to 13a 3*a*4-2*a*2+5*a-10 evaluates to 13a-10 Multiply a and a couple of Multiply a and a million The a in simple terms receives copied alongside. the reply is a a 2*a evaluates to 2a Multiply 4 and 2a Multiply a million and a The a in simple terms receives copied alongside. a 2*a*4 evaluates to 8a Multiply a and four Multiply a and a million The a in simple terms receives copied alongside. the reply is a a 4*a evaluates to 4a Multiply 2 and 4a Multiply a million and a The a in simple terms receives copied alongside. a 4*a*2 evaluates to 8a 2*a*4+4*a*2 evaluates to 16a Multiply a and 5 Multiply a and a million The a in simple terms receives copied alongside. the reply is a a 5*a evaluates to 5a 2*a*4+4*a*2+5*a evaluates to 21a 2*a*4+4*a*2+5*a-2 evaluates to 21a-2 To subtract the polynomials 13a-10 and 21a-2 we attempt to subtract words in a unmarried polynomialwith any like words in the different polynomial. Be very careful with the "-" examine in the front of 21a-2 it truly is for use on all words in it. 13a - 21a = -8a -10 - -2 = -8 the reply is -8a-8 (3*a*4-2*a*2+5*a-10)-(2*a*4+4*a*2+5*a-2) evaluates to -8a-8 the spectacular answer is -8a-8
