Question

Can you explain the answer of this question below:The sum of two zeroes of the polynomialf(x) = 2x2+(p+3) x+5 is zero, then the value of &#8216;p&#8217; isA:4B:&#8211; 4C:3D:&#8211; 3The answer is d.

Answer

Answer

Alpha + beta =-b/a
means coefficient of x / coefficient of x
and a general form of a equation is

K( x²+( ā+b)x+ā×b)
given is that
ā+b=0
therefore
p+3=0
&p=-3
answer d is correct

Answer

Let the two zeros of the polynomial be a and b.
Since the sum of the zeros is zero, we have a + b = 0.
By Vieta's formulas, the sum of the zeros of a quadratic polynomial ax^2 + bx + c is -b/a.
In this case, we have -b/a = 0, which means b = 0.
Since the product of the zeros is equal to c/a, we have ab = 5/2.
Since b = 0, we have a(0) = 5/2, which means a = 5/2.
Therefore, the value of a is 5/2.

Answer

No c
