Question

solve the quadratic equation

(2x+1)(x-3)=0

Answer 1

x= -1/2 U x= 3

Answer 2

Step by step solution :

Step 1 :

Multiply 2x+1 by x-3
Equation at the end of step 1 :

(2x + 1) • (x - 3) = 0
Step 2 :

Solve (2x+1)•(x-3) = 0
A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.We shall now solve each term = 0 separately.


Solving a Single Variable Equation :

Solve : 2x+1 = 0

Subtract 1 from both sides of the equation :
2x = -1
Divide both sides of the equation by 2:
x = -1/2

Solving a Single Variable Equation :

Solve : x-3 = 0

Add 3 to both sides of the equation :
x = 3
Two solutions :

x = 3
x = -1/2
