Factorise 8x^2 + 10x + 3

Step-by-step explanation:

so 8^2 +10x+3 (if you times 8*3 -gives you 24)

the middle number is 10X right so then you have to guess two numbers that either add up or take away to make it a positive 10.

so example if i try 5+5 it gives me 10 but it i multiply 5 by 5 -it gives 25 therefore lets try another pair of numbers.

i chose 6 and 4 because when i add them it gives me 10 and when i multiply them, it gives me 24.

therefore im just going to:

8x^2+6x+4x+3

to factorise im going to use 2x

2x(4x+3) + 1(4x+3)

so my answer is (2x+1) and (4x+3)
