Hii friend!!
x² + 3x - 10 = 0
x² - 2x + 5x - 10 = 0
x(x-2) + 5(x-2) = 0
(x-2)(x+5) = 0
→ x-2 = 0 ; x = 2
→ x+5 = 0 ; x = -5
Therefore, 2 and -5 are zeroes of the polynomial
Hope it helps
x² + 3x - 10 = 0
x² - 2x + 5x - 10 = 0
x(x-2) + 5(x-2) = 0
(x-2)(x+5) = 0
→ x-2 = 0 ; x = 2
→ x+5 = 0 ; x = -5
Therefore, 2 and -5 are zeroes of the polynomial
Hope it helps
