Use synthetic substitution to find /(-2) for S(x) = - 2x - x + 10.

Pick the expression that matches this description: a polynomial of the 5th degree with a leading coefficient of 7 and a constant term of 6 (choice a) 7x^5+2x^2+6 (choice b) 7x^6−6x^4+5 (choice c) 6x^7−x^5+5 (choice d) 6x^5+x^4+7

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b

Iknow its nothing to do with education, but what type of thing should i wrote here? ? : ) its for mcdonald's btw.
