Question

On of the zeros of the polynomial
2x²14x-4 is
​

Answer 1

Step-by-step explanation:

wrong ques

there should be an operator between 2x² and 14x. but there is no operetor

Answer 2

Answer:

2x²-14x-4=0

Step-by-step explanation:

2(x²-7x-2)=0

2 goes r.h.s and divide by zero then result is zero

x²-7x-2=0

so x²-7x-2 is discriminate

diccriminate process

b²-4ac

so where

a=1

b=-7

c=-2

(-7)²-4(1)(2)=49-8=41

D<0 that ha no real roots

D>0 that has roots

D=0 that may have one root

. .discriminat has some roots
