Answer:

ANSWER: (t-1)*(t-2)*(t-3)

Explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "t2" was replaced by "t^2". 1 more similar replacement(s).

STEP1:

Equation at the end of step 1

(((t3) - (2•3t2)) + 11t) - 6

STEP2:

Checking for a perfect cube

t3-6t2+11t-6 is not a perfect cube

Trying to factor by pulling out :

Factoring: t3-6t2+11t-6

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: 11t-6

Group 2: -6t2+t3

Pull out from each group separately :

Group 1: (11t-6) • (1)

Group 2: (t-6) • (t2)

t3-6t2+11t-6

can be divided by 3 different polynomials,including by t-3

dividend t3 - 6t2 + 11t - 6

- divisor * t2 t3 - 3t2

remainder - 3t2 + 11t - 6

- divisor * -3t1 - 3t2 + 9t

remainder 2t - 6

- divisor * 2t0 2t - 6

remainder 0

Quotient : t2-3t+2 Remainder: 0

Factoring t2-3t+2

wich gives you (t-1)*(t-2)*(t-3)

Answer:-4098

Explanation:

if t=6, then x(t)=6³-66²+42

6³=216 and -66²=-4356

216-4356+42= -4140+42=-4098

lmk if it’s wrong and ill edit it
