Can you tell me how to factorise 6b+24bc
Kamila [148]
When we factorise an expression, we are looking for simple factors that multiply to get the original expression. Usually it is very natural to factorise something like a quadratic in x. For example:

x^2 + 3x + 2 = (x+1)(x+2)

But there are other situations where factorisation can be applied. Take this quadratic:

x^2 - 9x = x(x-9)

This second example is closer to the question in hand. Just like x was a common factor to both x^2 and -9x, we are looking for a common factor to both 6b and 24bc. The common factor is 6b.

Hence 6b + 24bc = 6b(1 + 4c).

I hope this helps you :)

Hey there!!

(1) Both the angles sum up to be 180.

(2) Both the angles sum up to be 90

_________________

(1) 4x+5+8x-5=180

... 12x=180

... x= 180/12

... x = 15

________________

(2) 4z+3z+6=90

... 7z+6=90

... 7z=84

... z=84/7

... x=12
