Subtract (3x^2-x^3)-(-5x^3+2x^2+1)

your answer is .

Step-by-step explanation:

4x^3+x^2-1

Step-by-step explanation:

(3x^2-x^3)-(-5x^3+2x^2+1)

Distribute the minus sign

(3x^2-x^3)+5x^3-2x^2-1

Combine like terms

-x^3 +5x^3  + 3x^2 -2x^2 -1

4x^3+x^2-1

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
