Question

x²+9x+10>0 using by
quadratic inequality
​

Answer 1

Step-by-step explanation:

The first term is, x2 its coefficient is 1 .

The middle term is, -9x its coefficient is -9 .

The last term, "the constant", is -10

Step-1 : Multiply the coefficient of the first term by the constant 1 • -10 = -10

Step-2 : Find two factors of -10 whose sum equals the coefficient of the middle term, which is -9 .

-10 + 1 = -9 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -10 and 1

x2 - 10x + 1x - 10
