Answer:
- 1
Step-by-step explanation:
2x + 3 = x - 4
2x - x = - 4 + 3
x = - 1
The solution to the above equation is - 1.
Notice that half of the coefficient of x is (1/2)(-4), or -2.
Then x^2 - 4x becomes
x^2 - 4x + 4 - 4 = 0, or (x -2)^2 = 4. Then x = -2 plus or minus 2, and the two roots are 0 and -4.
Thus, add 4 to both sides to obtain x^2 - 4x + 4 = 4.
