Question

एक्स स्क्वायर प्लस 4 एक्स माइनस 5 इज इक्वल टू जीरो​

Answer 1

Answer:

x²+4x-5=0

x²-x+5x-5=0

x(x-1)+5(x-1)=0

(x+5)(x-1)=0

x=-5 or 1

Answer 2

Step-by-step explanation:

p(x)=x^2+4x-5=0

p(0)=(0)^2+4(0)-5=0

=0×0+4×0-5=0

=0+0-5=0

=0-5=0

=-5 doesn't equal to 0

p(1)= (1)^2+4(1)-5=0

=1×1+4×1-5=0

=1+4-5=0

=5-5=0

=0=0
