10x (7x² +9x +6 )

multiply
—————

10x (7x²) + 10x (9x) +10x (6)

70x³ + 90x² + 60x

simplification
———————

10x (7x² +9x + 6)

10x(7x² + 9x +6)

7x² + 9x + 6 is a quadratic equation ,
in the form of ax² + bx + c
we know , for any quadratic have real roots only when Discriminant=b² -4ac ≥0

D = b² -4ac =(9)² -4 x 7 x 6

D = 81 -168 = -87 <0

hence, no real roots exist of 7x²+9x +6

hence, we can't factorise ,

so, simplest form of this is ------

10x(7x² +9x + 6)

10x (7x²) +10x(9x)² + 10x(6)²

70x³ +90x² + 60x this is simplest form of given expression .

What is the equation of the line that passes through (2, -7) and (-1, 2)?
SVETLANKA909090 [29]

Answer:

y = -3x - 1

Step-by-step explanation:

The slope intercept form of the equation of a line is:

y = mx + b

where m is the slope, and b is the y-intercept.

First, we find the slope of the line using the two given points.

m = slope = (y2 - y1)/(x2 - x1) = (2 - (-7))/(-1 - 2) = (2 + 7)/(-3) = 9/(-3) = -3

Now we plug in the slope we found into the equation above.

y = -3x + b

We need to find the value of b, the y-intercept. We use the coordinates of one of the given points for x and y, and we solve for b. Let's use point (2, -7), so x = 2, and y = -7.

y = -3x + b

-7 = -3(2) + b

-7 = -6 + b

Add 6 to both sides.

-1 = b

Now we plug in -1 for b.

y = -3x - 1
