Question

product
find sum of zeroes and
polynomial x² + 7x + 12.
of
​

Answer 1

Answer:

Now, let's solve it by splitting the middle term. Here, addition of 4x and 3x is 7x & Multiplication of 4x and 3x is 12 x²., which is correct. So, zeros are -4 and -3. We have quadratic polynomial = x² + 7x + 12.

hope it helps

Answer 2

Answer:

Let p(x) =x^2+7x+12

=x^2+3x+4x+12

=x(x+3)+4(x+3)

=(x+3)(x+4)

x+3=0 ; x+4=0

x=-3 ; x=-4

thus the zeroes of p(x) are -3 and -4

So, sum of zeroes=-3+(-4)=-3-4=-7=-(-7)/1=-b/a
