Question

find the zero of the polynomial P(x)=2xsquare-5x-3

Answer 1

2x^2 - 5x - 3 = 0

2x^2 - 6x + x - 3 = 0

2x(x - 3) + 1(x - 3) = 0

(2x + 1)(x - 3) = 0

So, x = -1/2 or x = 3

Answer 2

Answer:

Step-by-step explanation:

2x×x-5x+3

2x×x-2x-3x+3

2x(x-1)-3(x-1)

(2x-3)(x-1)

2x-3=0

2x=3

X=3/2

X-1=0

X=1

P(1)=2×1-5×1+3

=2-5+3

=-3+3

=0

P=1//
