The value of x for which the expressions 3x – 4 and 2x + 1 become equal is
-3
0
5
1

Step-by-step explanation:

To determine for which value of x a pair of expressions will be equal, we will need to set them equal to each other and then solve for x.

First, we can add 4 to each side

Now we can subtract 2x from each side

Now, just to check our answer, we can plug in our answer back into the original equation to see whether we get the same result for each side

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

ok
