Answer 1

Answer:

please mark me as BRINEST.

Step-by-step explanation:

given

p(x) = 10x²+3x-4

10x²+8x-5x-4

2x(5x+4)-1(5x+4)

(2x-1)(5x+4)

2x-1 = 0

2x = 1

x = 1/2

5x+4 = 0

5x = 4

x = 4/5

zeroes are 1/2 & 4/5

verification between zeroes and coefficients

a = -b/a

1/2 = -3/10

B = c/a

4/5 = -4/10

4/5 = -2/5
