Web7 x 4 = 28 . correct me if im wrong . 2. what are the factors of -28 Answer: The factors of 28 are the numbers, which on multiplication in pairs results in the original number. These factors are 1,2,4,7,14 and 28. Since, 2 x 14 = 28, therefore (2,14) is a pair factor of number 28. Step-by-step explanation:. 3. what are the factor of 28 Answer: WebThe factored form of the polynomial is (x−2)(3x−4)(x-2)(3x-4)(x−2)(3x−4)left parenthesis, x, minus, 2, right parenthesis, left parenthesis, 3, x, minus, 4, right parenthesis.

WebAnd then we can solve each of these. Subtract 5 from both sides. You get 2x is equal to negative 5. Divide both sides by 2. You could get one solution is negative 5/2. Over here, add 5 to both sides. You get 2x is equal to positive 5. Divide both sides by 2. You get x could also be equal to positive 5/2. So both of these satisfy that equation ... WebTo solve the equation, factor x^{2}-3x-40 using formula x^{2}+\left(a+b\right)x+ab=\left(x+a\right)\left(x+b\right). To find a and b, set up a system … WebWe have an a squared minus a b squared. So in this case, a is equal to x and b is equal to 7y. So we have x squared minus 7y, the whole thing squared. So we can expand this as the difference of squares, or actually this thing right over here is the difference of squares. So we expand this like this. So this will be equal to x plus 7y times x ... cell phone snake
