87.1 = \frac{[ ( 1.96 + x ) 10 ] ^{2}}{( 15 - 12 ) ^{2}}

x = 0.83982 \dots, x = - 4.75982 \dots

Solution steps

87.1 = \frac{[ ( 1.96 + x ) \cdot 10 ] ^{2}}{( 15 - 12 ) ^{2}}

Switch sides

\frac{[ ( 1.96 + x ) \cdot 10 ] ^{2}}{( 15 - 12 ) ^{2}} = 87.1

Multiply both sides by

(15 - 12)^{2}

[(1.96 + x) 10]^{2} = 783.9

For

(g (x))^{2} = f (a)

the solutions are

g (x) = f (a), - f (a)

Solve

(1.96 + x) \cdot 10 = 783.9 : x = 0.83982 \dots

Solve

(1.96 + x) \cdot 10 = - 783.9 : x = - 4.75982 \dots

The solutions to the quadratic equation are:

x = 0.83982 \dots, x = - 4.75982 \dots

x^{2} - 6 x + 3 = 0

y + 9 = 13

\frac{x}{x - 5} > 0

7 y + 25 = 2 y

\frac{π}{12} + \frac{π}{3}
