The zeroes of the quadratic polynomial x^2 + 7x + 10 are1 point

Answer»

Answer:

- 5 & - 2

Step-by-step explanation:

= > x² + 7x + 10

Split the middle TERM in such a WAY so that the product of those parts will be equal to the product of FIRST and last term:

Here, 7 = 5 + 2 , as 5 * 2 = 10

= > x² + (5 + 2)X + 10

= > x² + 5x + 2x + 10

= > x(x + 5) + 2(x + 5)

= > (x + 5)(x + 2)

Hence,

Zeroes of this polynomial are - 5 & - 2.
