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

Asked by p.sownthra2006 | 15th Jun, 2021, 05:36: PM

Expert Answer:

x2 -7x+12= 0
→ x2 - 4x - 3x +12= 0
→ x(x - 4) - 3(x - 4)= 0
→ (x - 4)(x - 3) = 0
→ (x - 4) = 0 or (x - 3) = 0
→ x = 4 or x = 3

Therefore, the zeroes of the given quadratic polynomials are 4 and 3.
