Sqrt 24x 4th divided by sqrt 3x equals?

sqrt(24x4) / sqrt(3x) = sqrt(24x4/3x) = sqrt(8x3) = sqrt(2x times 4x2) = 2x sqrt(2x) or (2x)1.5


Square root 24x4 divided by square root 3x?

Sqrt(24x4)/Sqrt(3x) = Sqrt(24x4/3x) = Sqrt(8x3) = Sqrt(4x2*2x) = 2x*sqrt(2x)


Y equals 4x2 plus 6x - 1?

Y = 4x2 + 6x - 1Use the pq-formula:x = -4/2 +- sqrt ((4/2)2 -(-1))x = -2 +- sqrt((16/4) +1)x = -2 +- sqrt(4 +1)x1 = -2 + sqrt(5)x2 = -2 - sqrt(5)


Factor the following polynomial 4x2 - 169?

sqrt(4)=2 sqrt(169)=13 (2x+13)(2x-13)


Solution set for 4x2-6 equals 2x2?

Reading this as: 4x2-6=2x2 This implies that: -6=-2x2 3=x2 x=sqrt(3) and x=-sqrt(3) So x can equal plus or minus the square root of 3

Could you help me to 4x2-4x plus 1 equals 9?

Probably a quadratic equation problem.4X2 - 4X + 1 = 94X2 - 4X - 8 = 0factor out a 4 looks like a dead end, so....X = - b (+/-) sqrt(b2 - 4ac)/2aa = 4b = - 4c = - 8X = - (- 4) (+/-) sqrt[(- 4)2 -4(4)(- 8)]/2(4)X = 4 (+/-) sqrt(16 + 128)/8X = 4 (+/-) sqrt(144)/8X = [4 (+/-) 12]/8================X = 2X = - 1

Square root 2a?

Whether or not the expression can be simplified depends on the value of a. In general, sqrt(2a) = sqrt(2)*sqrt(a).


Do you put an absolute value sign for a variable if there is still a value under the radical?

if value means a constant that doesn't contain a perfect square as in abs(sqrt(2x)) vs abs(sqrt(2))abs(sqrt(x)) then the former is better, but if theres an extractable perfect square then 2*abs(sqrt(3x)) is preferred to abs(2*sqrt(3x)) or abs(sqrt(12x)).


Can a value in a square root be negative?

Yes, but it involves the square root of -1. sqrt (-X) = sqrt (X) * sqrt(-1)
