Question

Hello guys!

i challenging in social science can anybody answer this question

correct answer should be appreciated​ ​

Answer 1

Step-by-step explanation:

• 4x^2-x-5
• 4x^2+4x-5x-5
• 4x(x+1)-5(x+1)
• (4x-5)(x+1)=0
• 4x-5=0; x+1=0
• x=5/4 ; x =1

verification :

• from the above Q. P
• a=4,b=-1,c=-5
• let zeroes are alpha=5/4;beta=1

sum of the roots =-b/a

• alpha +beta =-(-1)/4
• (5/4)+1 =1/4
• 9/4 =1/4

product of the roots =c/a

• alpha *beta = -5/4
• (5/4)(1) =-5/4
• 5/4 =-5/4
