Question

2x2-5x+7
Find The roots vy splitting middle term Method​

Answer 1

Answer:

your question is wrong before 7 the sign will be negative

then the answer will be

2x²-(2x-7x)-7

=(2x²-2x)+(7x-7)

=2x(x-1)+7(x-1)

=(2x+7)(x-1)

Answer 2

Answer:

Step-by-step explanation:

multiply 1st and last term

2*7=14 and find the factors of 14

put -7x+2x instead of -5

2x²-7x+2x+7

x(2x-7)1(2x+7)

x+1=0, 2x-7=0

x=-1,x=7/2
