Given that a^­­b = x, evaluate the following: 2a^3b +a^2b+ a^b

2x^3+x^2 +x = x(2x^2 +x+1)

Step-by-step explanation:

a^­­b = x,

2a^3b +a^2b+ a^b=

2(a^b)^3+(a^b)^2 +a^b=

2x^3+x^2 +x=

x(2x^2 +x+1)

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
