if x^2 = 49, then the square root property says you can take the square root of both sides as long as you make one a plus-minus. x^2 = 49, which means square root of x^2 = plus minus the square root of 49 the square root of 49 is 7, so +- 7. We get: x = plus/minus 7 (this means either positive 7 or negative 7)
Plus or minus 7.
The given expression is 4 - √28. Since 28 contains a perfect square factor, we can simplify √28 to get: 4 - √(4 * 7) = 4 - √(2² * 7) = 4 - 2√7
The square root of 28 minus the squared root of 7 =±2.64575131
X2+5x-6. a=1, b=5, and c=-6 The formula is: -b plus or minus the square root of b squared minus 4ac all over 2a. -b+square root of b2-4ac ---- 2a -5 plus or minus the square root of 5 squared minus 4(1)(-6) -5 plus or minus the square root of 25-4(-6) -5 plus or minus the square root of 25+24 -5 plus or minus the square root of 49 -5 plus or minus 7 Here is where you split into two different answers: Number 1: -5 plus 7= 2 Number 2: -5 minus 7= -12 Your answer is X=2, -12

Plus or minus 7.
X = -1 or +3.
As stated, the question does not make sense: x square root of 4 is x2 or 2x, as it is more conventionally written. There is no term for 2x in the expansion of x - 3*sqrt(7)
The given expression is 4 - √28. Since 28 contains a perfect square factor, we can simplify √28 to get: 4 - √(4 * 7) = 4 - √(2² * 7) = 4 - 2√7
square root -5 minus 14 or - square root -5 minus 14
The solution to -3 times the square root of 184 divided by 4 is approximately equal to -12.94.
Expressed in root form, 5 sqrt(18) - 7 sqrt(8) = sqrt(2)
