The quadratic function h(x) = x² + 7x - 30 has h(3) = h(-10) = 0
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
h(3) = h(-10) = 0
Hence the zeros are at x = 3 and x = -10
(x - 3) = 0; and (x + 10) = 0
h(x) = (x - 3)(x + 10)
h(x) = x² + 7x - 30
The quadratic function h(x) = x² + 7x - 30 has h(3) = h(-10) = 0
