Question

Find the real solutions using quadratic formula

Answer 1

`\bf \begin{array}{lcclll} 1x^2&+8x&-5&=0\\ 1x^2&-8x&-5&=0\\ \uparrow &\uparrow &\uparrow\\ a&b&c \end{array} \qquad \qquad x= \cfrac{ - {{ b}} \pm \sqrt { {{ b}}^2 -4{{ a}}{{ c}}}}{2{{ a}}}`

so hmm do so then, the quadratic formula is very straightforwards, just plug in your values
