Answer» Answer: hope its helps to you Step-by-step explanation: Given One ZERO of the polynomial x2 - 2x - (7P + 3), find the value of p and the other zero. ANSWER Given f(x) = x^2 – 2 x – (7 p + 3) Given one zero of polynomial f(x) = - 4 and other zero be a So sum of zeroes = coefficient of x / coefficient of x^2 -4 + a = - (- 2)/1 -4 + a = 2 a = 2 + 4 = 6 The other zero is 6 Now product of zeroes = constant term / coefficient of x^2 -4 x 6 = - (7 p + 3) / 1 -24 = - (7 p + 3) 7 p + 3 = 24 7 p = 24 – 3 7 p = 21 P = 3 So the value of p is 3 |
