Question

m
m². – 25 + 100 factorise​

Answer 1

Answer:

Since its a quadratic polynomial, we can factorize it by splitting the middle term. To split its middle term, we need to find two numbers whose product is 100 and sum (in this case) is 25. The two numbers are -20 and -5 because -20-5 = -25 and (-20)*(-5) = 100.

Answer 2

Answer:

m2= -25+100

= 75

m2= 75

m=√75
