Question

Represent the zeros of the quadratic polynomial x2+7x+10 graphically

Answer 1

Given:

Quadratic polynomial x²+7x+10

To find:

The zeroes of the given polynomial

Solution:

1) A Quadratic polynomial is the equation of the variable x with degree 2.

2) We will first solve this by splitting the middle term method,

• x²+7x+10

• x²+5x+2x+10

• x(x+5)+2(x+5)

• (x+2)(x+5)

so the zeroes of the equations will be -2 and -5.

Graphical represent is given below.

The zeroes of the given polynomial -2 and -5
