Question

4) Solve the following quadratic equations
iv) (2 + 1)x² (5-1) x+2 (1-1)=0​

Answer 1

Answer:

$\Large\boxed{x=0}$

Step-by-step explanation:

To solve quadratic equations, first you have to find the value of x to use quadratic equations form. Remember to solve this problem, you have to isolate by the x on one side of the equation.

Given:

(2+1)x²(5-1)x+2(1-1)=0

First, you have to rewrite the problem down. (refine).

$\displaystyle (2+1)x^2(5-1)x=0$

Solve.

$\displaystyle 12x^3=0$

Solution:

Secondly, divide by 12 from both sides.

$\displaystyle \frac{12x^3}{12}=\frac{0}{12}$

Solve.

$x^3=0$

Apply by the rule of:

ₓᵃ=0 → x=0

Finally, the correct answer is x=0.
