Question

plz ans the viii one guyz

Answer 1

here friend see in this question ,first factories it by splitting the middle term;







i think u didn't get the factors!! right







ohk then see here
x^2+13x-11x-143!!!

now i hope u can do it!!! right

Answer 2

x^2+2x-143
d=√b^2-4ac
d=√2^2-4(1)(-143)
d=√4+572
d=√576
d=√4*144
d=2√144
d=2*12
d=24
root = d/2a
=24/2(1)
=12

d=√b^2+4ac
=√4-572
=√-568
Root = d/a
=√-568/2

Hence zeros
r / Factorisation is 12,√-568/2

Hope its helpful pls mark it as a brain list answer plssssssssssssssssssssssssssssssssssss
