Question

Write the smaller solution first and the larger solution second -4x^2-7=-11

Answer 1

x= 1

x= -1

Explanation:

`- 4x^(2) - 7 = - 11 \\ subtract \: both \: sides \: by \: 7 \\ \\ - 4x^(2) = - 4 \\ divide \: both \: sides \: by \: - 4 \\ \\ x^(2) = ( - 4)/( - 4) \\ divide \: - 4 \: to \: - 4 \\ \\ x ^(2) = 1 \\ take \: square \: root \: of \: both \: sides \: of \\ the \: equation \\ \\ x = 1 \\ x = - 1`
