Complete the square to transform the quadratic equation into the form

The square of a binomial is written like

$(x\pm a)^2 = x^2\pm 2ax + a^2$

In your case, you have $2ax=-8x$ , which implies $a=-4$

So, we want to write

$(x-4)^2 = x^2-8x+16$

But our left hand side is

$x^2-8x-10$

If we add 26 to both sides, we have

$x^2 - 8x - 10 +26 = 18+26 \iff x^2-8x+16=44 \iff (x-4)^2=44$

The top two answers are equivalent, while the bottom one is not. You would use distributive property in the parentheses. If both expressions are the same, they are equivalent

What are the solution(s) for the quadratic equation?

MariettaO [177]

Let's see

$\\ \rm\rightarrowtail x^2+12x+36=0$

$\\ \rm\rightarrowtail x^2+6x+6x+36=0$

$\\ \rm\rightarrowtail x(x+6)+6(x+6)=0$

$\\ \rm\rightarrowtail (x+6)(x+6)=0$

$\\ \rm\rightarrowtail x=-6$
