Question

(4x-7)^2

Answer 1

what about it?

Answer 2

16x^2+49

Answer 3

Would that be the answer?

Answer 4

do you want to expand it ?

Answer 5

Is there anything to expand?

Answer 6

get it out of the brackets

Answer 7

i put it into my cas and i got 16x^2-56x+49

Answer 8

and then if you want x just solve to get x= 7/4

Answer 9

did that help staldk3?

Answer 10

So it wouldn't be x^3 for the 16x part?

Answer 11

So 16x^3+49?

Answer 12

I don't think I have to solve for x

Answer 13

im confused on what you are looking for next time please be more precise. then people can help you quicker

Answer 14

I think I just need to solve (4x-7)^2 and I don't have to solve for x

Answer 15

solve probably means solve for x because if they wanted it to be simplified they would have wanted you to expand and collect like terms

Answer 16

Okay. Can you show me how to do that?

Answer 17

(4x-7)^2 =(4x-7)(4x-7) = 16x^2 -28x -28x +49 = 16x^2 -56x +49

or if you know formula

(a-b)^2 = a^2 -2ab +b^2

than in your presently case a = 4x and b = -7

so using these and introduced in this formula will get the same result


hope this will help you understanding easy right sure
