# How do you factorise 8x plus 12?

###### Answered 2020-12-14 11:24:17

first you divide both sides by 2 then add brackets in front of the number:

1. divide 8x+12= 4 and 6 divide again = 4 and 2 and 3

2. add brackets= 4{2x=3}

Do you mean 2x&sup2;? Assuming this is the case: 2x&sup2; - 3x + 8x - 12 = 2x&sup2; + 5x - 12 = (2x - 3)(x + 4)

the factor that can be divided perfectly into 8 and 12 is 4 4(2x2+3) then you have factorised

You don't. There is no way to factorise it.

If you mean: xsquared+8x-48 then it factors to (x-4)(x+12)

Doesn't factorise in integers. Roots are 0.84 and 7.16

16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11

Use www.wolframalpha.com Enter factor 4x^2+8x-5 to receive the answer (2x-1)(2x+5)

I assume you mean...., 8X + 16 8(X + 2) ======

If the equasion is 12x+6-8x-4x-3+12 then the answer is 15.

8x - 9 = 11x + 12 8x = 11x + 21 -3x = 21 x = -7

You take out the common factor, in this case, 8x. To get the other factor, divide both monomials by 8x.

4(2x-3)+7=8x8x-12+7=8x-8x..........-8x-12+7=0+12.....+127=12-7...-7No Solution:0&ne;54(2x-3+7)=8x8x-12+28=8x-8x............8x-12+28=0+12.......+1228=12-28...-28No Solution: 0&ne;-16

8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4

16x - 8x + 12 = 78 + 22 or simplified to (16x-8x=8x)(78+22=100) 8x + 12 = 100 Simplify some more (Subtract 12 from both sides) 8x = 88 Divide both sides by 8, and x = 11

28=8x+12-7x 28=8x-7x+12 28=x+12 28-12=x+12-12 16=x
