Complex solutions, namely roots with a √(-1) or "i" in it, never come all by their lonesome, because an EVEN root like the square root, can have two roots that will yield the same radicand.
a good example for that will be √(4), well, (2)(2) is 4, so 2 is a root, but (-2)(-2) is also 4, therefore -2 is also a root, so you'd always get a pair of valid roots from an even root, like 2 or 4 or 6 and so on.
therefore, complex solutions or roots are never by their lonesome, their sister the conjugate is always with them, so if there's a root a + bi, her sister a - bi is also coming along too.
if complex solutions come in pairs, well, clearly a cubic equation can't yield 3 only.
Is it 1-4/5 x 5/12 or 4/5 x 12
Answer:
= 7.878
Step-by-step explanation:
Answer:
Step-by-step explanation:
Add you like terms. 4x plus 4x equals 8x. Then 5 plus 9 equals 14 so then you have 8x= 14 divide by eight on both sides and there you go.
