5/3x = ? ; where x = 90
90/1 times 5/3
cross simplification
now it's 30/1 times 5/1 i divided the numerator of the first fraction and the denominator of the second fraction by 3
now it is 5 times 30
so... 5/3 of a 90 degree angle is 150 degrees
Answer:
x=1+2i/2
Step-by-step explanation:
Using the method of completing the square
(2x)²-2(2x)1 +(1)²+4=0
(2x-1)²=-4
taking square root on both sides
2x-1=2i
2x=1+2i
x=1+2i/2
Answer:
(3x + 4)(x - 1)
Step-by-step explanation:
3x^2 + x - 4
use middle term break method
we need two number which gives 12 when multiplied and 1 when subtracted
3x^2 + (4 - 3)x - 4
3x^2 + 4x - 3x - 4
x(3x + 4) -1(3x + 4)
(3x + 4)(x - 1)
