Q. (6t4−t+1)−(6t3−4t)Which of the following expressions is equivalent to the given expression?Choose 1 answer:(A) 6t4−6t3+3t+1(B) 6t4−6t3−5t+1(C) 3t+1(D) −5t+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.(6t4−t+1)−(6t3−4t) becomes 6t4−t+1−6t3+4t.
Combining Like Terms: Now, we combine like terms. There are no other t4 or t3 terms, so they remain as they are. The t terms are −t and +4t, which combine to +3t. The constant term is +1.So, the expression becomes 6t4−6t3+3t+1.
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. 6t4−6t3+3t+1 is the simplified form, and there are no further like terms to combine.
