Question

if a minus b and a + b are zeros of polynomial 2 x cube minus 6 x square + 5 x minus 7 find the value of a​

Answer 1

a+b+a-b=0

0=8-36-35

a = -63 +/-  b

Answer 2

Answer:

Step-by-step explanation:

Let r1 and r2 be the zeroes of the polynomial

r1 = a - b (Given)

r2 = a + b (Given)

P(x) = 2x^3 + 6x^2 + 5x - 7
