The square root of 28 minus the squared root of 7 =±2.64575131
I suggest you use the quadratic formula, with a = 3, b = -2, c = 7.
It depends. Is the entire expression squared or just radical 7?Assuming the latter, then 6 + (√7)^2 = 6 + 7 = 13.
7
6√5 + 2√5 - 7 = 8√5 - 7, which cannot be simplified.
(x+4)(x-7)
4 x2
x(x - 7)
2(x + 7)(x - 7)
x(x - 7)
5-(-2) =7 The answer is 7.
