Question

let us solve 2(x²-4)=3(x²-4)
​

Answer 1

Answer:

2

Step-by-step explanation:

${2x}^{2} - 8 = {3x}^{2} - 12 \\ = {2x}^{2} - {3x}^{2} = 8 - 12 \\ = - {x}^{2} = - 4 \\ = {x}^{2} = 4 \\ x = \sqrt{4} \\ = x = 2$

Answer 2

Answer:

x=2

Step-by-step explanation:

2(x^2-4)=3(x^2-4)

2x^2-8=3x^2-12

-8=3^2-12-2^2

-8+12=3^2-2^2

4=1x^2

1x^2=4

x^2=4/1

x^2=4

x=√4

x=2
