Step by Step

How do you find the factors or zeroes of a polynomial (or the roots of a polynomial equation)? Basically, you whittle. Every time you chip a factor or root off the polynomial, you’re left with a polynomial that is one degree simpler. Use that new reduced polynomial to find the remaining factors or roots.

At any stage in the procedure, if you get to a cubic or quartic equation (degree 3 or 4), you have a choice of continuing with factoring or using the cubic or quartic formulas. These formulas are a lot of work, so most people prefer to keep factoring.....

Answer 2

Step-by-step explanation:

STEPS OF CONSTRUCTION:

1.Draw line segment of length AB=8cm.

2. Draw any Ray AX making acute ∠BAX with AB

3. Draw a parallel to BY parallel to AX by making∠ABY=∠BAX.

. Then it intersect AB at a point P.

Thus P is the point of dividing AB internally in the ratio 3:4.
