Question

Simplify.

x^2 - 36 over 42 x - 7 x^2

Answer 1

Is this your question:\[\frac{x^2-36}{42x-7x^2}\]

Answer 2

yes

Answer 3

\[\huge \frac{x^2 - 36}{42x - 7x^2} \implies \frac{(x+6)(x-6)}{7x(6 - x)}\]

Answer 4

i just factored it out

Answer 5

do you know how to solve the problem now??

Answer 6

no

Answer 7

your like a lightning bolt @lgbasallote

Answer 8

remember that (a-b) = -(b-a) therefore \[\huge \frac{(x+6)(x-6)}{7x(6 - x)} \implies \frac{(x+6)(x-6)}{-7x(x-6)}\]
now do you know how to solve it?

Answer 9

I have no idea

Answer 10

hint find the number in the top and bottom then cancel out or get rid off after that u know how to solve it

Answer 11

remember that \[\huge \frac{ab}{ad} \implies \frac{\cancel a b}{\cancel a d} \implies \frac bd\]

Answer 12

that look the same
