The 10th term of an a.p is -27 and the 5th term is -12 .find the first term?

horsena [70]

Step-by-step explanation:

$a_{10} = - 27... (Given) \\\\\therefore a + 9d = - 27...... (1)\\\\a_{5} = - 12... (Given) \\\\\therefore a + 4d = - 12.......(2)\\\\$

Subtracting equation (2) from equation (1)

$a + 9d-( a + 4d )= - 27-(-12)\\\\\therefore a +9d - a-4d = - 27+12\\\\\therefore 5d = - 15\\\\\therefore d = \frac {- 15}{5}\\\\\huge \orange {\boxed {\therefore d = -3}} \\\\$

Substituting d = - 3 in equation (1), we find:

$a + 9\times (-3)= - 27\\\\\therefore a - 27 = - 27\\\\\therefore a = 27- 27\\\\\huge \red {\boxed {\therefore a = 0}}\\\\$

Hence, first term is zero.

6x^2 + 66x + 60 factor completely

kiruha [24]

Hi! Let me help you!

Remember, factoring looks like so:
ab+ac=a(b+c)
So, we need to find the greatest common factor (G.C.F.) of the polynomial.
In this case, 6 is the GCF, so we factor it out:
6x²+66x+60
Divide 6, 66 and 60 by 6:
x²+11x+10

<u>Answer:</u>

x²+11x+10

Hope you find it helpful.

What are the rational roots of the polynomial f(x) = 20x^4 + x^3 +8x^2 + x-12

Natali5045456 [20]

Answer:

x = 3/4 and x = -4/5

Step-by-step explanation:

20x⁴ + x³ + 8x² + x − 12

Group:

(20x⁴ + 8x² − 12) + (x³ + x)

Factor:

4 (5x⁴ + 2x² − 3) + x (x² + 1)

4 (5x² − 3) (x² + 1) + x (x² + 1)

(x² + 1) (4 (5x² − 3) + x)

(x² + 1) (20x² + x − 12)

(x² + 1) (4x − 3) (5x + 4)

So the rational roots are x = 3/4 and x = -4/5.
