simplify the expression to a polynomial in standard form:
(3x-4)(x^2-5x-1)

3x3−19x2+17x+4

Step-by-step explanation:

(3x−4)(x2−5x−1)

=(3x+−4)(x2+−5x+−1)

=(3x)(x2)+(3x)(−5x)+(3x)(−1)+(−4)(x2)+(−4)(−5x)+(−4)(−1)

=3x3−15x2−3x−4x2+20x+4

=3x3−19x2+17x+4

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

the discriminant is 64 + 4*1*12 = 112

this is prime.
