Step by step solution :
- Step 1 :Pulling out like terms. 1.1 Pull out like factors : 8x – 48 = 8 • (x – 6) Equation at the end of step 1 :
- Step 2 : 2.1 Divide both sides by 8. Solve Basic Inequality : 2.2 Add 6 to both sides. x < 6. Inequality Plot : 2.3 Inequality plot for. 8.000 X – 48.000 < 0.
What are the factors of x2 49?
Rewrite 49 as 72 . Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 – b 2 = ( a + b ) ( a – b ) where a=x and b=7 .
Can x2 8 be factored?
Check : 8 is not a square !! Ruling : Binomial can not be factored as the difference of two perfect squares.
How many solutions does 8x 56 have?
The equation 8x = 56 has only one solution.
Is x2 49 a prime polynomial?
The polynomial x2−49 x 2 – 49 is not prime because the discriminant is a perfect square number.
How to calculate the factoring of x2 + 8x-48?
Factor x2 + 8x−48 x 2 + 8 x – 48 using the AC method. Tap for more steps… Consider the form x 2 + b x + c x 2 + b x + c. Find a pair of integers whose product is c c and whose sum is b b. In this case, whose product is − 48 – 48 and whose sum is 8 8.
Which is the correct way to solve X ^ 2-8x-48?
x ^ 2 -8x -48 = 0 Quadratic equations such as this one can be solved by a new direct factoring method that does not require guess work. To use the direct factoring method, the equation must be in the form x^2+Bx+C=0.
How to calculate the sum of X ^ 2-8x-48?
First, left hand side needs to be rewritten as x^ {2}+ax+bx-48. To find a and b, set up a system to be solved. Since ab is negative, a and b have the opposite signs. Since a+b is negative, the negative number has greater absolute value than the positive. List all such integer pairs that give product -48. Calculate the sum for each pair.
Which is the correct formula to solve Factor X 2?
To solve the equation, factor x 2 − 8 x − 4 8 using formula x 2 + ( a + b) x + a b = ( x + a) ( x + b). To find a and b, set up a system to be solved. Since ab is negative, a and b have the opposite signs.
