What is X squared +3x-70

Mathematics
1 answer:
Aleksandr-060686 [28]4 years ago
8 0

Answer:

x = 7, x = -10

Step-by-step explanation:

x^2+3x-70 = 0

Use the quadratic formula.

x = \frac{-3 + \sqrt{3^2-4(1)(-70)} }{2(1)} \\x = \frac{-3 - \sqrt{3^2-4(1)(-70)} }{2(1)} \\

Solve.

x = 7, x = -10

You can also factor if you want - that is a faster method.

Order these expressions for least to greatest:
Sever21 [200]

Answer:

^3sqrt(-27), ^3sqrt(-8), 0, ^3sqrt(8), ^3sqrt(27), sqrt(10), 6, 8

Step-by-step explanation:

You just need to convert these to decimals to figure it out.

In our case

^3sqrt(-27) = -3

^3sqrt(-8) = -2

^3sqrt(8) = 2

^3sqrt(27) = 3

sqrt(10) = 3.16

So...

-3, -2, 0, 2, 3, 3.16, 6, 8
