Can you please help me solve this and show the solution 4y⁴+6y?​
Pepsi [2]

Answer:

4y^4 + 6y = 256y + 6 = <u>262y</u>

Step-by-step explanation:

Remove the variables for a second and think of the problem as a normal expression; 4^4 + 6

Simplify the first term; 4^4 = 256

Now, add 6; 256 + 6 = 262

Add back in the variable; 262y

Solve quadratic equation 10x^2+x-2=0
zhuklara [117]

Answer:

\{-\frac{1}{2} \} \cup \{\frac{2}{5}\}

Step-by-step explanation:

10x^2 + x - 2 = 0; \\ a = 10, b = 1, c = -2; \\ D = b^2 - 4ac = 1^2 - 4 * 10 * (-2) = 1 + 80 = 81 = 9^2, > 0; \\ x_{1, 2} = \frac{-b \pm \sqrt{D}}{2a} = \frac{-1 \pm \sqrt{9^2}}{2 * 10} = \frac{-1 \pm 9}{20} = \left \ [ {{\frac{-1 - 9}{20} = -\frac{10}{20} = -\frac{1}{2}  } \atop {\frac{-1 + 9}{20} = \frac{8}{20} = \frac{2}{5}}} \right.
