Number 1 and 2 : don't you know how to solve a quadratic
when
Use this formula to factor degree two polynomials (#3)
hey if you can solve one or all of them it will be much appreciated. Please show all work. thanks!
(^2=squared)
solve:
1: 5x^2+x=-3
2: 4(x-2)^2=20
Factor:
3: 9x^2+15x-36
write as a complex number in standard form:
4: 1+3i/3+4i
complete the square:
5: x^2-8x+4=0
find the absolute value:
6: (2-3i)
7: write a quadratic function in vertex form, whose graph has the given vertex and passes through the given point:
vertex: (-6,-7) point (0,-6)
8: write a quadratic function in intercept form whose graph has the given x-intercepts and passes through the given point:
x-int: (-2,7) points (8,18)
these problems are for a take home quiz and i want to make sure i did them 100% correctly.
