Subtract 5 to both sides so that the equation becomes -2x^2 + 6x - 1 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -6 ± √((6)^2 - 4(-2)(-1)) ] / ( 2(-2) )
x = [-6 ± √(36 - (8) ) ] / ( -4 )
x = [-6 ± √(28) ] / (-4)
x = [-6 ± 2*sqrt(7) ] / (-4 )
x =3/2 ± -sqrt(7)/ 2
The answers are 3/2 + sqrt(7)/2 and 3/2 - sqrt(7)/2.
Answer:
9,375
Step-by-step explanation:
Each number is multiplied by 5 to get the next number. We can see this by testing multiple number on this set of data.
3*5=15
15*5=75
75*5=375.
Thus, to find the next term in the set of data, we must multiply the last number that we are given by 5.
1875*5=9,375
The next number is 9,375
Hope this helps!
