Question

find zero of following
2 x square minus root 5 x minus 50 ​

Answer 1

Answer:

2×√-5×√-5×-50=-500

Step-by-step explanation:

• If we square the root, the root will cancel.
• If we multiply minus with minus the minus will change to plus.

Answer 2

Answer:

2x square - √5 X - 50=0

2x square - 5√5 X + 4√5 X - 50=0

x(2x - 5√5) +2√5(2x - 5√5)=0

(X +2√5)(2x-5√5)=0

X+2√5=0 & 2x-5√5=0

X=-2√5 & X = 5√5/2

Hence,zeros of equation is -2√5 & 5√5/2
