How many total roots are must there be in this function explain how you know
h(x)=x3-7x2-x+7

total 3 roots,

How do I know?:

put this function in graphing calculator

And if you don't have a graphing calculator, then calculate it out bu yourself:

(x + 1)(x − 1)(x − 7) = 0

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

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

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
