The answers to that would be x=-2
2*10^8
the exponent would be 8
hope this helps!
Answer:
a.) 9, -9
b.) 2(sqrt)15, -2(sqrt)15
c.) 4, -2+2i(sqrt)3, -2-2i(sqrt)3
d.) 3(sqrt)75
(some of the numbers are placed differently than I wrote them so here are screenshots- pls look at them rather than what I wrote ;w;)
A. First move all to the left side of the equation(Normal form)
x^3 - 49x= 0
B. Factor out an x, which is the GCF (Factored form)
x(x^2 - 49) = 0
C. Find solutions by making each x piece equal to 0. The first part is just x=0 and the second part is just factoring the difference of squares and then solving.
x=0, x^2 - 49 =0
x=0, x + 7 = 0, x - 7 = 0
Therefore, the answers for Part C are:
x = 0, x = -7, x = 7
