The square of 4x - 49 = 0 is solved by factorization

The square of 4x - 49 = 0 is solved by factorization

4X squared - 49 = 0
(2x+7)(2x-7)=0
x=-7/2 x=7/2

How to do x square - 4x = 8 with factorization?

x²-4x+4=12
(x-2)²=12
x-2=±2√3
x=2+2√3 x=2-2√3

The square of X + 4x = 10 and the square of X - 6x = 11 are made by matching method

Square of X + 4x = 10
x²+4x+4=14
（x+2）²=14
x+2=±√14
x=-2±√14
The square of X - 6x = 11
x²-6x+9=20
(x-3)²=20
x-3=±2√5
x=3±2√5

Please use the matching method to match the vertex formula of quadratic function y = - 4x square + root 6x root 3

Er
Y = - 4 (x ^ 2 - √ 6 / 4x) - √ 3
Then y = - 4 (x ^ 2 - √ 6 / 4x + 3 / 32-3 / 32) - √ 3
Then y = - 4 (x - √ 6 / 8) ^ 2 + 3 / 8 - √ 3
end
