Question

Find the quadratic polynomial whose zeroes are -2 and -5.
Verify the relationship between zeroes and coefficients of
the polynomial.
Please send quick on paper pic

Answer 1

Step-by-step explanation:

Let the zeros are a and b

• a=-2
• b=-5

We know that equation of the line

$\boxed{\sf x^2-(a+b)x+ab}$

$\sf \longmapsto {x}^{2} - ( - 2 - 5)x + ( - 2)( - 5) = 0\\ \sf \longmapsto {x}^{2} - ( - 7)x + 10 = 0 \\ \bf \longmapsto {x}^{2} + 7x + 10 = 0$

Answer 2

Answer:

Let the zeros are a and b

a=-2

b=-5

We know that equation of the line
