Question

find the zeroes of quadratic polynomial p(x)=2x-15-x^2 ​

Answer 1

Answer:

ok so first of all

we have to consider this equation as 0 ( dont ask why. we have to take it as default )

Step-by-step explanation:

2x² - 15 - x²  = 0

arrange correctly

x² - 2x² - 15

x² + 5x - 3x - 15 = 0

x ( x + 5 ) +3 ( x - 5 )

(x+ 3) (x - 5 )

x = -3

x = 5

these are the zeros of px
