Answer:
x = 0
Step-by-step explanation:
add 7 to each side to get:
2x² = 0
divide each side by 2 to get:
x² = 0
take square root of each side to get:
x = [tex]\sqrt{0}[/tex]
x = 0
Answer:
x = 0
Step-by-step explanation:
[tex] {2x}^{2} - 7 = - 7[/tex]
[tex] = {2x}^{2} = 0[/tex]
[tex] = {2x}^{2} \div 2 = 0 \div 2[/tex]
[tex] = {x}^{2} = 0 \div 2[/tex]
[tex] = {x}^{2} = 0[/tex]
[tex] = x = 0[/tex]
