Eden · Answer

Hint: To find the prime factors, we will divide the number by the lowest prime number. We will repeat this until the number is no longer divisible by that number. Then we will divide it with the next prime number and repeat this process until the number is completely factored with all the factors as prime numbers

solve the quadratic equation x2 + 3x = 10 by factorization method

Factorise by splitting the middle term
s2 – s – 9
(s square – s – 9)
