Solve 2 a 2 − 5 a − 25 = 0 by factoring. Enter your answers below a = or a =
kaheart [24]

Answer:

a=5, a=-2.5

Step-by-step explanation:

<em>Given:</em>

<em />2 a^2 - 5 a - 25 = 0

<em>Solution:</em>

<em />a_{1,\:2}=\frac{-\left(-5\right)\pm \sqrt{\left(-5\right)^2-4\cdot \:2\left(-25\right)}}{2\cdot \:2}

a_{1,\:2}=\frac{-\left(-5\right)\pm \:15}{2\cdot \:2}

a_1=\frac{-\left(-5\right)+15}{2\cdot \:2},\:a_2=\frac{-\left(-5\right)-15}{2\cdot \:2}

a=5,\:a=-2.5

Hello,

\boxed{sin^4\ x= \frac{3}{8}- \frac{cos\ 2x}{2}+\frac{sin\ 4x}{8}  }\\&#10;&#10;Let's assume t=6x \ dt=6\ dx\\&#10;&#10; \int\limits {sin^4\ 6x} \, dx =  \frac{1}{6} *\int\limits {sin^4\ t} \, dt \\&#10;&#10;= \dfrac{1}{6} *( \frac{3t}{8} - \frac{sin\ 2t}{4} +\frac{sin\ 4t}{32})+C\\&#10;&#10;= \dfrac{3x}{8} - \frac{sin\ 12x}{24} +\frac{sin\ 24x}{192} +C&#10;
