Answer:
(x +3)(x -3)(x +2i)(x -2i)
Step-by-step explanation:
The factoring to quadratics makes use of the fact that -36 = (-9)(4).
x^4 -5x^2 -36
= x^4 -9x^2 +4x^2 -36
= x^2(x^2 -9) +4(x^2 -9)
= (x^2 +4)(x^2 -9)
The form for factoring the difference of squares comes into play here. Of course -4 = (2i)^2.
= (x^2 -(2i)^2)(x^2 -3^2)
= (x -2i)(x +2i)(x -3)(x +3) . . . factored to linear terms
Answer:
x=12.4
Step-by-step explanation:
First subtract 134 ft with 10 and then you divide it by 10 to get 12.4.
Answer: A=2, B=5, C=4
Step-by-step explanation:
So A=2, B=5, and C=4.
5-2*3+6(3^2+1)
5-2*3+6(10)
5-2*3+60
5-6+60
59
59=59
True
147 is not a prime number 147= 49 * 3
49 is divisable by 7: 49= 7 * 7
7 is not divisable by anything
