Question

solve using the square root property: 4a^2-45=0

Answer 1

Let, 4a2 = 45,
a2 = 45/4,
a = radical 45/4.....

Answer 2

actually

Answer 3

a = +/- radical 45/4.....

Answer 4

the answer is positive or negative 3 radical 5 divided by 2 i just dont know how to get it

Answer 5

\[\Large 4a^2 - 45 = 0\]


\[\Large 4a^2 = 45\]


\[\Large a^2 = \frac{45}{4}\]


\[\Large a = \pm\sqrt{\frac{45}{4}}\]


\[\Large a = \pm\frac{\sqrt{45}}{\sqrt{4}}\]


\[\Large a = \pm\frac{3\sqrt{5}}{2}\]

Answer 6

thank you!!!!!!!!!!!!!!!
