Question

Find the zeroes of the quadratic polynomial x2+7x+12

Answer 1

Answer:

Answer x is equal to -3, -4

Answer 2

x² + 7x + 12

= x² + 3x + 4x + 12

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

= (x + 3)(x + 4)

To find the zeroes,

x + 3 = 0 => x = -3

or, x + 4 = 0 => x = -4

Thus, -3 and -4 are the zeroes of the given polynomial.
