(u+15)(u-3)=(u+16)(u+2)

(u + 15) (u - 3) = (u + 16) (u + 2)

u = - \frac{77}{6}

Decimal Notation

u = - 12.83333 \dots

Solution steps

(u + 15) (u - 3) = (u + 16) (u + 2)

Expand

(u + 15) (u - 3) : u^{2} + 12 u - 45

Expand

(u + 16) (u + 2) : u^{2} + 18 u + 32

u^{2} + 12 u - 45 = u^{2} + 18 u + 32

Move

45

to the right side

u^{2} + 12 u = u^{2} + 18 u + 77

Subtract

u^{2} + 18 u

from both sides

u^{2} + 12 u - (u^{2} + 18 u) = u^{2} + 18 u + 77 - (u^{2} + 18 u)

Simplify

- 6 u = 77

Divide both sides by

- 6

u = - \frac{77}{6}

5 x - 17 = - x + 7

\frac{x ^{4} y ^{5}}{x ^{3} y ^{2}}

970 \cdot 2^{\frac{11}{4}}

- \frac{3}{4} x \geq - \frac{9}{16} + \frac{1}{3} x

1 6^{2 n} < 8^{n + 5}
