Question

8. Souve sath equation by gracking, Round to the nearest tenth.Z 4B = -7%0-7-6, -16,-11,5

Answer 1

Step 1: Write out the equation

`x^2+6=-7x`

Step 2: Rewrite the equation

`x^2+7x+6=0`

Step 3: Plot the graph of y = x² + 7x + 6

Step 4: Find the solution of the equation x² + 7x + 6 = 0

The solutions of x² + 7x + 6 = 0 are the x-coordinates of the points where the curve y = x² + 7x + 6 cuts the x-axis.

From the graph, we can see that the points are (-6, 0) and (-1, 0)

Hence, the solutions are -6, -1
