The general solution of the equation tan x = 1 is

Tangent function is positive when the angle is a multiple of π/4 or 5π/4. Since the period of the tangent function is π, the general solution is: x = π/4 + π*k x = 5π/4 + π*k Where k is an integer co

Find the number that should be added to each expression to make it a perfect square

1. x²- 10x 2. z²+ 7z-(a+b)^2 = a^2 + 2ab + b^2 so a^2 = x^2 (we can say a = x) 2ab = 10x here we want to divine b since we already said a = x then 10 must be 2b which means b = 5 and b^2 is 25 The sa

Solve Each Equation By Completing the Square. Please show me or help me

1) k^2 + 8k + 12 = 0 2) a^2 - 2a - 48 = 0 3) x^2 + 12x + 20 =0 4) m^2 - 12m + 26 = 0 5) p^2 - 8p +21 = 6 6) a^2 - 2a - 8 = 0-Half the middle term in this case 8k/2 is 4k then 4 goes into the brac
