How to solve x^2>4x+3

1 answer:

7 0

Treat this as you would the quadratic equation x^2 - 4x - 3 + 0. Solve this by completing the square:

x^2 - 4x + 4 - 4 - 7 = 0

(x^2 - 4x + 4) = 11

(x-2)^2 = 11, and so x-2 = plus or minus sqrt(11).

Graph this, using a dashed curve (not a solid curve). Then shade the coordinate plane ABOVE the graph.

Simplify. 12k - 6 + (3k)(4) Is it -6, 6, 24k + 6, or 24k - 6?

Effectus [21]

It's 24k-6

By order of operations, you do the multiplication first: 3k(4) = 12k

12k-6+12k now combine like terms

24k-6
