factorise the polynomial X square + X - 10...what is the answer please solve fast...I will mark u brainliest but no wrong answer please

(x + + )(x + - )

Step-by-step explanation:

solve the polynomial for x then express in product of factor form

Solve

x² + x - 10 = 0 ( add 10 to both sides )

x² + x = 10

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2( )x + = 10 +

(x + )² = ( take the square root of both sides )

x + = ± = ± ( subtract from both sides )

x = - ±

Thus corresponding factors are

(x - (- - ) ) and (x - (- + ), that is

(x + + ) and ( x + - )

Thus

x² + x - 10 = ( x + + )(x + - ) ← in factored form
