1.0, 2.1, 3.2, 4.3 5.4, 6.5, 7.6,
Step-by-step explanation:
p²-5p-14=0
p²-7p+2p-14=0
p(p-7)+2(p-7)=0
(p-7)(p+2)=0
either,
p-7=0
p=7
or,
p+2=0
p = -2
hope it helps.
Answer:
B
Step-by-step explanation:
Answer:
10+15i/13
Step-by-step explanation:
This question is about complex numbers.
so,
in this type of questions we have to multiply this fraction by the conjugate of the denominator
conjugate of the denominator is 3-2i
1) 5i(3-2i)/(3+2i)(3-2i)
2) 15i-10i^2/9-4i^2 ( we know that i^2 = -1 )
3) 15i+10/9+4
4) 15i+10 / 13
