The curve y = 2x^3 + ax^2 + bx + 7 has a stationary point at the point (2,-13). a Find the value of a and the value of b.
b Find the coordinates of the second stationary point on the curve.
c Determine the nature of the two stationary points.
d Find the coordinates of the point on the curve where the gradient is minimum
and state the value of the minimum gradient.​

207/8 is the right

i think asking google will you get the answer to that question

28

step-by-step explanation:

because that's the answer

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
