Question

factorise 9xsquare - 24x+25​

Answer 1

Step-by-step explanation:

The first term is, 9x2 its coefficient is 9 .

The middle term is, +24x its coefficient is 24 .

The last term, "the constant", is +25

Step-1 : Multiply the coefficient of the first term by the constant 9 • 25 = 225

Step-2 : Find two factors of 225 whose sum equals the coefficient of the middle term, which is 24 .

-225 + -1 = -226

-75 + -3 = -78

-45 + -5 = -50

-25 + -9 = -34

-15 + -15 = -30

-9 + -25 = -34

For tidiness, printing of 12 lines which failed to find two such factors, was suppressed

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored
