Question

factorise
3x²-15x+18 and find the roots of the polynominal​

Answer 1

Answer:

2 and 3

Step-by-step explanation:

3x^2 - 15x + 18 = 0

3x^2 - (9+6)x + 18 = 0

3x^2 - 9x - 6x + 18 = 0

3x (x - 3) - 6 (x - 3) = 0

(3x - 6)(x - 3) = 0

The two zeroes/roots are :-

3x - 6 = 0

3x = 6

=) {x = 2}

&

x - 3 = 0

=) {x = 3}
