Question

What are the zeroes of the quadratic polynomial x? + 7x + 12
O (a) 4,3
O (b) 4,-3
O (c) -4,3
O (d) -4,-3​

Answer 1

Step-by-step explanation:

To find zero of the polynomials simply factor it..

x^2 + 7x + 12

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

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

=(x+3)(x+4)

means x+3 , x+4 will give zeros...

Hence zeros are-

x = -3

x= -4

Answer 2

Answer:

4 and 3

Step-by-step explanation:

=x2+7x+12

=x2+(4x+3x)+12

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

=(x+4)(x+3)
