simplify (2x-7)^2 not sure of the answer?

( 2x - 7 ) ( 2x - 7 )

4x² - 28x + 49

(2x-7)(2x-7)
4x^2-14x-14x+49
=4x^2-28x+49

(2x - 7)^2
= (2x - 7)(2x - 7)
= 2x*2x - 7*2x - 2x*7 + 7*7
= 4x^2 - 14x - 14x + 49
= 4x^2 - 28x + 49

4x^2 - 28x + 49

u jst expand it like these
(2x-7)(2x-7)

(2x-7)^2
(2x-7) (2x-7)
4x^2 -28x + 49

2x-7 2

4x^2-28x+49

Okay, we need to get the x variables on one side of the equals sign. 1. Subtract x/18 from both sides. 2x/9 - 5/72 - 1/24 - (x/18) = x/18 + 1/36 - (x/18) 2x/9 - 5/72 - 1/24 - x/18 = 1/36 2. Get all the non-x fractions on the other side by adding 5/72 and 1/24 to both sides 2x/9 - 5/72 + (5/72) - 1/24 + (1/24) - x/18 = 1/36 + (5/72) +(1/24) 2x/9 - x/18 = 1/36 + 5/72 + 1/24 3. Now we need to get common denominators so that we can do the adding and subtracting. On the x side, the lowest common denominator is 18, as 9 and 18 both go into 18. On the non-x side, our lowest common denominator is 72, as 36 goes into 72 twice and 24 goes into 72 three times. You will need to also multiply the numerator (top number) by the same number you multiply the denominator. (2x/9)2 - x/18 = (1/36)2 + 5/72 + (1/24)3 4x/18 - x/18 = 2/72 + 5/72 + 3/72 4. Now we simply add and subtract the numerators while keeping the denominators constant. (4x - x)/18 = (2+5+3)/72 5. Now we simplify. 3x/18 = 10/72 We can divide 3x/18 by 3 to simplify, and 10/72 by 2 x/6 = 5/36 Multiply both sides by 6 6(x/6) = 6(5/36) The 6's cancel out x = 30/36 x = 5/6
