Answer 1

Step-by-step explanation:

2x²+8x-10

2x²+10x-2x-10

2x(x+5)-2(x+5)

(x+5)(2x-2)

please make me brilliant

Answer 2

Answer:

2[(x+5)(x-1)] or (x+5)(2x-2)

Step-by-step explanation:

Using cumulative property:

2(x^2+4x-5)

Factor out (x^2+4x-5), we have:

2[(x+5)(x-1)]

Another way

2x^2+8x-10

Since, 5 x - 2 = -10

And (1 x -2) + (5 x 2) = +8

We have this answer:

(x+5)(2x-2)
