Step-by-step explanation:
in complex numbers i²=-1
Answer:
(x-5)(x+3)
Step-by-step explanation:
x^2-2x-15
factor out the trinomial
(x-5)(x+3)
Answer:
Step 1
Step-by-step explanation:
Correct solution step-by-step:
1. 5(x + 2) = 6x + 12
2. 5x + 10 = 6x + 12
3. 5x - 6x = 12 - 10
4. -x = 2
5. x = -2
Answer:
x^2=5-x
x^2+x-5=0
x=-1± √(1)^2-4(1)(-5) /2(1)
-1± √21 /2
