5 th no question plz factorisation trinomials plz answer anyone

Answer 1

Step-by-step explanation:

x2 +15x+56

x2+7x +8x +56

x(x+8)+7(x+8)

(x+8)(x+7)

Answer 2

Step-by-step explanation:

given quadratic equation is xsquare - 15x + 56=0

solution:

x square - 15 x + 56 = 0

x square - 7 x - 8x+ 56 =0

x square ( x-7) - 8 (x-7) = 0

taking (x-7) (x-8) =0

(x-7) and (x-8) Are the two factors of given quadratic equation

and

x=7 , 8 @re the roots of equation....
