Question

which are the roots quadratic equation m²-14m+13=0

1) 13,1
2) -13,-1​

Answer 1

Answer:

by splitting the middle term,

Step-by-step explanation:

${m}^{2} + m + 13m + 13 = 0 \\ m(m + 1) + 13(m + 1) = 0 \\ (m + 13)(m + 1) = 0...$

Answer 2

Answer:

13,1

Step-by-step explanation:

m^2-14m+13=0

m^2-13m-m+13=0

m(m-13)-1(m-13)=0

(m-1)(m-13)=0

m-1=0 or m-13=0

m=1 or m=13

hence roots are 13 and 1
