Determine the factors of 3x2 + 10x − 8. (Which is the right answer?)

VMariaS [17]

ANSWER

$(3x - 2)(x + 4)$

EXPLANATION

The given quadratic trinomial is

$3 {x}^{2} + 10x - 8$

Comparing to the general quadratic trinomial:

$a{x}^{2} + bx + c$

We have a=1, b=10 and c=-8

$ac = 3 \times - 8 = - 24$

The factors of -24 that adds up to 10 are -2 and 12.

We split the middle term to obtain;

$3 {x}^{2} + 12x - 2x- 8$

Factor;

$3x(x+ 4) - 2(x + 4)$

Factor further;

$(3x - 2)(x + 4)$

The last option is correct.

Which polygon has an interior angle sum of 1260°?

Liono4ka [1.6K]

Answer:

Step-by-step explanation:

Sum of interior angle of any polygon =(n-2) × 180°where n represents the number of sides in any polygon.

Or 1260 =(n-2)x180

Dividing both sides by 180:

7=n-2

Adding both sides by 2 we have :

n=9.

Hence a nanogon will have the sum of interior angles as 1260°.
