Question

the middle term of the expression 8x²+2x-15 is split into two numbers. The numerically large number is. a) positive b) negative c) neither positive nor negative​

Answer 1

Answer:

To Factorise : x

2

+2x−15

By splitting the middle term

=x

2

+5x−3x−15

=x(x+5)−3(x+5)

=(x−3)(x+5)

So, x

2

+2x−15=(x−3)(x+5)

solution
