Answer:
x(2x+13)
Step-by-step explanation:
Equation: [tex]2x^2+13x[/tex]
1). Apply exponent rule [tex]a^{b+c}=a^ba^c[/tex] ∴ [tex]2xx+13x[/tex]
Answer: 2x²+2•7 = 2(x²+7)17
Step-by-step explanation: 2x^2+13+2= 2x+15= 17
(2x2 + 13) + 2
Find roots (zeroes) of : F(x) = 2x2+15
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 2 and the Trailing Constant is 15.
The factor(s) are:
of the Leading Coefficient : 1,2
of the Trailing Constant : 1 ,3 ,5 ,15
Let us test ....
P Q P/Q F(P/Q) Divisor
-1 1 -1.00 17.00
-1 2 -0.50 15.50
-3 1 -3.00 33.00
-3 2 -1.50 19.50
-5 1 -5.00 65.00
-5 2 -2.50 27.50
-15 1 -15.00 465.00
-15 2 -7.50 127.50
1 1 1.00 17.00
1 2 0.50 15.50
3 1 3.00 33.00
3 2 1.50 19.50
5 1 5.00 65.00
5 2 2.50 27.50
15 1 15.00 465.00
15 2 7.50 127.50
2x2 + 15=17 so your over all answer is 17
