One x-intercept of 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= -x^2-5x-6
separate values with a comma

The other x-intercept is (-2,0)

Step-by-step explanation:

-x^2-5x-6

-(x^2+5x+6)

We know x=-3 is a x-intercept so x+3 is a factor

-(x+3)(        )

The other factor has to be x+2 since 3(2)=6 and 2+3=5

So -x^2-5x-6 is the same as -(x+3)(x+2)

Which means the other x-intercept is (-2,0)

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
