Question

factorise 3x2-x-10
it will be for10pt

Answer 1

3x²-6x+5x-10

= 3x(x-2)+5(x-2)

= (3x+5)(x-2)

Answer 2

Question:

Factorize $3{x}^{2} - x - 10$

Answer:

To factorize the polynomial

$f(x) = 3{x}^{2} - x - 10$

$f(x) = 3{x}^{2} -6x + 5x - 10$

$f(x) = 3x(x-2) +5(x-2)$

$f(x) = (3x + 5) (x-2)$

Factors are (3x + 5) and (x - 2)

NOTE:

• You have to write f(x), g(x) etc. before writing the given polynomial.
• It is important to write statement at the end.
