Answer:
Step-by-step explanation:
We want to find the solution to the equation:
Rearrange:
Combine like terms:
We can add five to both sides:
And divide both sides by five. Therefore:
Step-by-step explanation:
5√x+3 = -20
÷5. : √x+3 = -4
square: x+3 = 16
-3: x = 13
√x+18 -2 = x -4
+2 : √x+18 = x -2
square: x+18 = x^2 - 4x +4
-18: x = x^2 -4x -14
-x : 0 = x^2 -5x - 14
foil: (x- 7) (x+2) = 0
x = 7, -2
