Anyone know how to factorise this please ?! :)
raketka [301]

9514 1404 393

Answer:

  a) (x +2)(x +3)

  b) x = -2 or -3

Step-by-step explanation:

a) The constants in the binomial factors will be divisors of 6 that have a sum of 5. You know that ...

  6 = 1×6 = 2×3

The sums of these factor pairs are 7 and 5. You want the pair 2, 3. The factors are ...

  x² +5x +6 = (x +2)(x +3)

__

b) The solutions to the equation are the values of x that make the factors zero:

  (x +2) = 0   ⇒   x = -2

  (x +3) = 0   ⇒   x = -3

Expand and simplify= a+3b-(5a-4b)
lianna [129]

Answer:

1= -4a+7b

2=(7x-5)/3

Step-by-step explanation:

1,

a+3b-(5a-4b)

expand bracket 1st according to BIDMAS

a+3b-5a+4b

collect like terms

a-5a+3b+4b

ans=-4a+7b

2,

X/3+2x-5/3

solve for the 1st two

X/3 +2x

LCM =3 so,

(x+6x)/3=7x/3

use this and solve the last part

(7x/3)-(5/3)

LCM=3

ans=(7x-5)/3
