x^2+7x+8=2x+8 it is a quadratic equation or not
Answers
Answer:
s
its a quadratic equation
Step-by-step explanation:
I think it's correct
Answer:
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2".
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
x^2-7*x-(2*x-8)=0
Step by step solution :

Trying to factor by splitting the middle term
1.1 Factoring x2-9x+8
The first term is, x2 its coefficient is 1 .
The middle term is, -9x its coefficient is -9 .
The last term, "the constant", is +8
Step-1 : Multiply the coefficient of the first term by the constant 1 • 8 = 8
Step-2 : Find two factors of 8 whose sum equals the coefficient of the middle term, which is -9 .
-8 + -1 = -9 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -8 and -1
x2 - 8x - 1x - 8
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-8)
Add up the last 2 terms, pulling out common factors :
1 • (x-8)
Step-5 : Add up the four terms of step 4 :
(x-1) • (x-8)
Which is the desired factorization
Equation at the end of step
1
:
(x - 1) • (x - 8) = 0
