H(x) = 2x2 + 26 the fundamental theorem of algebra tells you that this polynomial function has x roots ?

From the fundamental Theorem of Algebra the given polynomial function has exactly 2 roots.

The fundamental Theorem of algebra states that:

If P(x) is a polynomial of degree n≥1 then P(x)=0 has exactly n roots, including multiplicity and complex roots.

Hence here we have a polynomial function h(x) as:

As the polynomial h(x) is of degree 2.

Hence, the polynomial h(x) has 2 roots.

goog may be able to you find that answer

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
