sorry i have no idea
standard form is ax^2+bx+c = 0. So, rearrange things and you have
7x^2 + 10x - 27 = 0
Better review the topic, as this was really quite easy.
7x^2 + 10x - 27 = 0
Better review the topic, as this was really quite easy.
The standard form of a quadratic equation :
a x² + b x + c = 0
27 = - 10 x - 7 x²
Subtract 27 to both sides
0 = - 10 x - 7 x² - 27
Since zero multiplied by any number is also zero, you can multiply both sides by - 1.
7 x² + 10 x + 27 = 0
a x² + b x + c = 0
27 = - 10 x - 7 x²
Subtract 27 to both sides
0 = - 10 x - 7 x² - 27
Since zero multiplied by any number is also zero, you can multiply both sides by - 1.
7 x² + 10 x + 27 = 0
