Q. (6t4t+1)(6t34t) \left(6 t^{4}-t+1\right)-\left(6 t^{3}-4 t\right) \newlineWhich of the following expressions is equivalent to the given expression?\newlineChoose 11 answer:\newline(A) 6t46t3+3t+1 6 t^{4}-6 t^{3}+3 t+1 \newline(B) 6t46t35t+1 6 t^{4}-6 t^{3}-5 t+1 \newline(C) 3t+1 3 t+1 \newline(D) 5t+1 -5 t+1
  1. Subtracting Polynomials: We need to subtract the second polynomial from the first one. To do this, we distribute the negative sign across the terms in the second polynomial and then combine like terms.\newline(6t4t+1)(6t34t)(6t^{4}-t+1) - (6t^{3}-4t) becomes 6t4t+16t3+4t6t^{4}-t+1 - 6t^{3}+4t.
  2. Combining Like Terms: Now, we combine like terms. There are no other t4t^4 or t3t^3 terms, so they remain as they are. The tt terms are t-t and +4t+4t, which combine to +3t+3t. The constant term is +1+1.\newlineSo, the expression becomes 6t46t3+3t+16t^{4} - 6t^{3} + 3t + 1.
  3. Checking the Expression: We check the expression to ensure there are no other like terms that can be combined and that all signs have been correctly distributed. 6t46t3+3t+16t^{4} - 6t^{3} + 3t + 1 is the simplified form, and there are no further like terms to combine.
