Question

7. Check whether (x-2)²=2(x-3) is quadratic or not. ​

Answer 1

Step-by-step explanation:

first we have to simply multiply all possible terms like,

here, in (x-2)^2 we are using identity of (a-b)^2

(x-2)(x+2)=2x-3x. (we have multiplied x-2 and

x+2)

x^2+2x-2x-4=2x-3x

now transfer all variables to left like,

x^2-4-2x+3x=0

now, in x^2+1x-4=0 or. {we always write

constant no. in last}

x^2-4-1x=0

so, as we can see the biggest

no. as exponential power

is 2.

and which term has biggest exponential power 2 so that equation is quadratic.
