Use the variation of parameters formula to find the general solution of the system x' (t) = ax(t) +f(t), where a and f(t) are given:
a = [ 8 -4 ] f(t) = [ t^-2 / 2 ]
[ 4 -2 ] [ t^-2 ]
fyi: a and f(t) are both matrices

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
