(x+y)(y−x), if x=−3; y=5

16

Step-by-step explanation:

Substitute x = - 3, y = 5 into the expression

(- 3 + 5)(5 - (- 3)), that is

(2)(5 + 3)

= 2 × 8

= 16

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

im guessing (23,14). hope this : )
