Answer:
x=-1 or x=4
Step-by-step explanation:
First divide by 4 to get rid of the factor 4 at x², then you have:
x² - 3x - 4 = 0
to factor that, look for two numbers that when added, give -3, and when multiplied, give -4. This is guesswork but usually doable:
-4 + 1 = -3
-4 * 1 = -4
so -4 and +1 are our numbers.
The factorization is therefore: (x - 4)(x + 1) = 0, and the solutions are
x-4 = 0 or x+1 = 0, so x=4 or x=-1
Expand and multiply
3^5 = 3 x 3 x 3 x 3 x 3 = 9 x 9 x 3 = 81 x 3 = 243
243 is your answer
hope this helps
