Answer:

I got -8/9

Step-by-step explanation:

Distribute the magical 1 in front of the parenthesis(-1) to 6x and -15 which become -6x and +15 and your new equation should be 3x + 25=2 - 6x + 15, 3x + 25=17 - 6x. Solve from their. Need more help just ask.

What is the solution of the following question?<br> x^2+10x+25=12

zalisa [80]

Make equal to 0
minus 12from both sides
x^2+10x+13=0
we can't factor so use quadratic formula

x= $\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}$
x= $\frac{-10+/- \sqrt{10^{2}-4(1)(13)} }{2(1)}$
x= $\frac{-10+/- \sqrt{100-52} }{2}$
x= $\frac{-10+/- \sqrt{48} }{2}$
x= $\frac{-10+/- 4\sqrt{3} }{2}$
x= $-5+/- 2\sqrt{3}$

x= $-5+ 2\sqrt{3}$ or $-5- 2\sqrt{3}$

aprox
x=-1.5359 or -8.4641
