Question

Solve 2x2 - 8x = -7.

Answer 1

\(\large\color{blue}{ 2x^2 - 8x = -7 }\)
\(\large\color{blue}{ 2(x^2 - 4x) = -7 }\)
\(\large\color{blue}{ 2(x^2 - 4x+4-4) = -7 }\)
\(\large\color{blue}{ 2(x^2 - 4x+4) -8= -7 }\)
\(\large\color{blue}{ 2(x^2 - 4x+4)= 1 }\)
\(\large\color{blue}{ (x^2 - 4x+4)= 1/2 }\)
\(\large\color{blue}{ (x-2)^2= 1/2 }\)
\(\large\color{blue}{ x-2= ±\sqrt{1/2} }\)
