Question

Solve?(:
x^2+8x-48=0

Answer 1

-b +- sqrt(b^2 - 4ac) / 2a

8 +- sqrt(64 - 4(1)(-48)) / 2(1)
8 +- sqrt(64 + 192) /2
8 +- sqrt(256) /2
8+- 16 /2

24/2 and -8/2 = 12 and -4

Hope that helps.

Answer 2

take 48 to lefthand side. Then add 16 to both sides and solve.

Answer 3

Factor the expression on the left.
x^2+8x-48=0
x^2 + 12x - 4x - 48 = 0
x ( x+12) - 4 ( x+12) = 0
(x-4)(x+12) = 0
(x-4) = 0 or (x+12) = 0 <- solve these two equations.

Answer 4

Those are ahrd equations.. i'll try.. Thanks! (:

Answer 5

I got.. -12 and 4?

Answer 6

That should be correct.

Answer 7
