Question

zero of the polynomiale (x+5)(x-2)

​

Answer 1

Answer:

(x+5)(x-2)

x²-2x+5x-10

x(x-2)+5(x-2)

x=2,x=-5

Answer 2

Answer:

$\large\bf\underline\blue{Given\:Polynomial:-}$

(x+5)(x-2)

$\large\bf\underline\blue{To\:Find:-}$

Zero of the polynomial

Step-by-step explanation:

(x+5)(x-2)

= x (x - 2) + 5(x - 2)

= x² - 2x + 5x - 10

= x² + 3x - 10

= x² + (5 - 2) x - 10

= x² + 5x - 2x - 10

= x ( x + 5) - 2 (x + 5)

= (x - 2)(x + 5)

x - 2 = 0

x = 2

x + 5 = 0

x = -5
