Question

Find the zeroes of the polynomial p(x) = 25 x2-35x + 12.

Answer 1

p(x) = 25x²-35x + 12

= 25x² +20x +15x + 12

=  5x (5x + 4) + 3(5x + 4)

= (5x + 3) (5x + 4)

x = -3/5

and x = -4/5

Answer 2

Step-by-step explanation:

$= 25 {x}^{2} - 20x - 15x + 12$

$= 5x(5x - 4) - 3(5x - 4)$

$= (5x - 3)(5x - 4)$

so four zeroes p(x)=0

x=3/5 or 4/5
