I think you mean 8x^2 + 7 =0
a = 8 b = 0 c = 7
x= [-b +- square root (b^2 - 4*a*c)] / 2a
x = [0 +-  square root (0 - 4*8*7)] / 2*8
x = +- square root (-224) / 16
x = +- <span> <span> <span> 14.9666295471 * i </span> </span> </span> / 16
x = + <span> <span> <span> 0.9354143467 </span> </span> </span> i
x = - <span> <span> 0.9354143467 </span> </span> i

Can someone help simplify?: -8x^3y2(2x^4y^4)
Kisachek [45]

So the rule with multiplying exponents of the same base is to add the exponents together. Applying this rule here would look like this:

-8x^3y^2*2x^4y^4=(-8*2)x^{3+4}y^{2+4}=-16x^7y^6

In short, your simplified expression is going to be -16x^7y^6.
