What are the solutions of x^2 = -7x-8
Vilka [71]

Solution, solve\:for\:x,\:x^2=-7x-8\quad :\quad x=\frac{-7+\sqrt{17}}{2},\:x=\frac{-7-\sqrt{17}}{2}

Steps:

x^2=-7x-8

\mathrm{Add\:}8\mathrm{\:to\:both\:sides},\\x^2+8=-7x-8+8

\mathrm{Simplify},\\x^2+8=-7x

\mathrm{Add\:}7x\mathrm{\:to\:both\:sides},\\x^2+8+7x=-7x+7x

\mathrm{Simplify},\\x^2+7x+8=0

Solve\:with\:the\:quadratic\:formula,\\\mathrm{For\:}\quad a=1,\:b=7,\:c=8:\quad x_{1,\:2}=\frac{-7\pm \sqrt{7^2-4\cdot \:1\cdot \:8}}{2\cdot \:1},\\x=\frac{-7+\sqrt{7^2-4\cdot \:1\cdot \:8}}{2\cdot \:1}:\quad \frac{-7+\sqrt{17}}{2},\\x=\frac{-7-\sqrt{7^2-4\cdot \:1\cdot \:8}}{2\cdot \:1}:\quad \frac{-7-\sqrt{17}}{2}

\mathrm{The\:final\:solutions\:to\:the\:quadratic\:equation\:are:},\\x=\frac{-7+\sqrt{17}}{2},\:x=\frac{-7-\sqrt{17}}{2}

\mathrm{Hope\:This\:Helps!!!}

a

\frac{2}{3}a-\frac{5}{6}a=2

a=2

\frac{4a-5a}{6}=2

4a−5a

=2

\frac{-a}{6}=2

6

−a

=2

-a=2\times 6−a=2×6

-a=12−a=12

a=-12a=−12

Therefore, the value of a will be -12.
