What are the solutions of the equation x4 – 5x2 - 36 = 0? Use factoring to solve.
balandron [24]

Answer:

x = -2i and x = 2i

x = 3 and x = - 3

Step-by-step explanation:

x^4 - 5x^2 - 36 = 0

let u = x^2 and substitute

we have:

u^2 - 5u - 36 = 0

(u - 9)(u + 4) = 0

u = 9 and u = - 4

substitute back for u

x^2 = 9

x = 3 and x = - 3

x^2 = -4 -- i am going to assume you've learned imaginary numbers; otherwise, you cannot take the square root of a negative number.

x = -2i and x = 2i

View the attached photo.

<span>The quadratic function, y = x2, has an x-intercept at the origin  = TRUE
</span>
<span>The quadratic function, y = x2 + 3, has an x-intercept at the origin = FALSE
</span>
<span>From x = -2 to x = 0, the average rate of change for both functions is positive = FALSE

When viewing a graph, you start from the left and go to right and from left to right from -2 to 0 the graph is declining.

</span><span>From x = -2 to x = 0, the average rate of change for both functions is negative = TRUE

Both are declining if you read the graph from left to right.

</span><span>For the quadratic function, y = x2, the coordinate (2, 3) is a solution to the equation of the function. = FALSE
</span><span>
y = x^2
If we insert 2 into y = x^2 we get y = 4 but our point (2,3) has y = 3

</span>For the quadratic function, y = x2 + 3, the coordinate (2, 7) is a solution to the equation of the function. = TRUE

If we insert 2 for x, we see that  y = x^2 + 3 =  y = 2^2 + 3 =  y = 7 and our y value in the point (2,7) is 7.
