Question

solve for x:-x²+16=0 also write the sum and product of zeroes (note-The question is not x²-16)​

Answer 1

Step-by-step explanation:

-x²+16=0

16-x²=0

4²-(x)²=0

(4-x)(4+x)=0

4-x=0. and 4+x=0

4=x. -4=x

+x²+ox+16=0

sum of zero = -b/a

= 0/-1

= 0

product of zero = c/a

= 16/-1

= -16
