Question

One x - intercept for a parabola is at the point (-3,0) . Use the factor Method to find the other x - intercept for the parabola defined by this equation y=-x2-5x-6

Answer 1

The other intercept of parabola is ( 6 , 0 ) and ( - 1 , 0)

Explanation:

Given as, the one intercept of parabola is ( - 3 , 0)

Now the parabola equation is y = x² - 5x - 6

So, So, for x - intercept , put y = 0

i.e x² - 5x - 6 = 0

Or, x² -6x + x - 6 = 0

So, (x - 6 ) (x + 1) = 0

So, x = 6 , - 1

Hence the other intercept of parabola is ( 6 , 0 ) and ( - 1 , 0) Answer
