(3/4, 0) and (5/2, 0) Solved with the help of the quadratic equation formula.

what is -12X squared +28X - 15? i figured it out myself. its (-6X + 5)(2X - 3).

x2 + 15x = -26x2 + 15x + 26 = -26 + 26x2 + 15x + 26 = 0 where a = 1, b = 15, and c = 26x = [-15 Â± âˆš(152 - 4(1)(26))]/2(1)x = (-15 Â± âˆš121)/2x = (-15 Â± 11)/2x = (-15 + 11)/2 = -4/2 = -2 or x = (-15 - 11)/2 = -26/2 = -13

14x2 + 29x - 15= 14x2 + 35x - 6x - 15= 7x(2x + 5) - 3(2x + 5)= (2x + 5)(7x - 3)

The x-axis is y = 0 → y = 8x² - 26x + 15 → 0 = 8x² - 26x + 15 = (4x - 3)(2x - 5) So 4x - 3 = 0 → 4x = 3 → x = ¾ = 0.75 or 2x -5 = 0 → 2x = 5 → x = 2½ = 2.5 The y-axis is x = 0 → y = 8x² - 26x + 15 = 8 × 0² - 26 × 0 + 15 = 15 → The points of contact with the x- and y- axes of y = 8x² - 26x + 15 are: (0.75, 0), (2.5, 0), (0, 15)

Equation: y = 8x^2 -26x+15 Equation when factorized: y = (4x-3)(2x-5) When x = 0 then y = (0, 15) which is the point of intersection on the y axis When y = 0 then x = (3/4, 0) and (5/2, 0) which are the points of intersection on the x axis

15 = 8x2 - 14x; whence, 8x2 - 14x - 15 = (2x - 5)(4x + 3) = 0. Therefore, x = 5/2 or -3/4.

The highest common factor of 15 and 45 is 15

You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x). Hope it helps :)

(x + 15)(x + 1)

8x2-2x-15 = 0 (2x-3)(4x+5) = 0 x = 3/2 or x = -5/4

Since 5 is a factor of 15, it is automatically the GCF.

The greatest common factor of 10y plus 15 is 5.

8x2-39x+45 = (8x-15)(x-3) when factored

15(3r - 4s + 1)

x2 + 8x + 15 = (x + 3)(x + 5)
