4) Solve the quadratic equation using the quadratic formula: 8x² - 10x - 2 = 0
FOR STANDARD QUADRATIC EQN.
AX^2+BX+C=,THE ROOTS ARE
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
HERE A=8...B=-10....C=-2...SO PUTTING IN THE FORMULA ,WE GET
x+=+%28-%28-10%29+%2B-+sqrt%28+%28-10%29%5E2-4%2A8%2A%28-2%29+%29%29%2F%282%2A8%29+
x+=+%2810+%2B-+sqrt%28+100%2B64+%29%29%2F%2816%29+
x+=+%2810+%2B-+sqrt%28+164+%29%29%2F%2816%29+
5) Solve the quadratic equation using the quadratic formula: 2x² - 5 = 4
6. Solve using the quadratic formula:
x² – 3x – 3 = -5
