Question

check whether quadratic equation(x-1)(x+2)= (x-4)(x-5)​

Answer 1

Answer:

NO

Step-by-step explanation:

quadratic equation has a form ax²+bx+c=0 where a≠0

so , from given

(x+1)(x+2)=(x+4)(x-5)

x²+2x+x+2=x²-5x+4x-20

x²-x²+2x+x-4x+5x+2+20=0

4x+22=0

since the co efficient is x²is zero it is not a quadratic equation.

Answer 2

Answer:

No........... It is linear equation

Step-by-step explanation:

(x-1) (x+2)= (x-4) (x-5)

X(x+2) - 1(x+2) = x(x-5) - 4(x-5)

X²+2x - x-2 = x²-5x-4x+20

X²-x² +2x+5x-x+4x - 2-20 = 0

7x+3x-22 =0

10x-22 =0
